点击此页面传一个值，并且此值会一直有效做法

参考博客：http://hutianci.iteye.com/blog/1015925

(1)在前台第一次进页面初始化时存值获取[在控件formValue存执]*/
OAFormValueBean oucdValue = 
         (OAFormValueBean)webBean.findChildRecursive("oucd");
oucdValue.setValue(pageContext, oucd);
/*(2)在后台第一次进页面初始化时存值获取：TransientValue是支持久化在本地JVM，
不会跨JVM持久化或Servlet Session范围保存。当root appliction module被回收
时，TransientValue会丢失*/
pageContext.putTransactionTransientValue("oucdValue",oucd);
String oucdValue =pageContext.getTransactionTransientValue("oucdValue").toString();

(3)设置全局变量(在类下设置)

--------------------------下拉框、LOV、隐藏-----------------------------

1、下拉框绑定事件(可直接在下拉框控件下绑定事件)

if ("changeList".equals(event)) {
         OAMessageChoiceBean totalInv = 
                   (OAMessageChoiceBean)webBean.findChildRecursive("totalInv");
         String selectValue = totalInv.getSelectionValue(pageContext);
         Serializable[] parameters = { selectValue };
         am.invokeMethod("handleListChangeEvent", parameters);
}

//Lov绑定事件点击手电筒 触发 lovPrepare 事件

//lovValidate手动修改Lov值时(点击别处时)触发事件
//lovUpdate从选择页面回主页面时触发事件
if ("lovUpdate".equals(event)) {
    String lovInputSourceId = 
     pageContext.getParameter(SOURCE_PARAM); //ID获取当前点击Lovinput控件的id
      if("categoryLovInput".equals(lovInputSourceId)) {
        ......
      }
}
if ("lovPrepare".equals(event)) {
         // txtSearch 为 LovInput 的条件框 
         OAFormValueBean txtSearch = 
                   (OAFormValueBean)webBean.findChildRecursive("category");
         // 设置 名称为 categoryClass 的 AM 参数 用于 传递到 LovInput的 page 页面中
         ((OADBTransaction)am.getTransaction()).putTransientValue("category", 
                                                                  txtSearch.getText(pageContext));
    }
//在 LovInput Page 的CO 中processRequest 添加
//获取刚刚从主页面设置的 参数
    String txtSearch = 
            (String)pageContext.getTransactionTransientValue("category");
                           
以类别和等级为例：其中只要类别为Lov时，可以在类别lovMapping下的lovMap对应
LOV Region Item设置值为：ParentFlexValueLow，
Criteria Item值设置为：对类别Id，
设置Programmatic Query设置为：True

2、hideShow控件控制:设置其展示和隐藏功能

OADefaultHideShowBean hideShow1 = 
 (OADefaultHideShowBean)webBean.findChildRecursive("hideShow1");
hideShow1.setDefaultDisclosed(pageContext,false);
(如果是利用其他控件进行控制，则需要进行刷新页面)
注意：此处不是OAHideShowBean类、对应属性设置也不是setDisclosed

//动态控件值的获取(控件属性动态时)

String[] departs = {"departmentCho"};
HashMap dpts =CustomSearchUtil.getBeanValues(pageContext,webBean,departs);  
String departments = dpts.get("departmentCho")+"";
3、控件
  public static HashMap getBeanValues(OAPageContext pageContext, OAWebBean webBean, 
                                          String[] strWebBeanNames)
  {
    HashMap searchMap = new HashMap();
    if (strWebBeanNames != null)
    {
      OAWebBean itemWebBean =null;
      for (int i = 0; i       {
        //Search for Bean
        itemWebBean =webBean.findChildRecursive(strWebBeanNames[i]);
                   Object valueStr = null;
                   String value = "";
        if (itemWebBean !=null)
        {
         //OAMessageTextInputBean
          if(itemWebBean instanceof OAMessageTextInputBean)
          {                      
                       valueStr =((OAMessageTextInputBean)itemWebBean).getValue(pageContext);
           //((OAMessageTextInputBean)itemWebBean).setValue(pageContext, null);
          }
         //OAMessageLovInputBean
          else if(itemWebBean instanceof OAMessageLovInputBean)
          {
            valueStr = ((OAMessageLovInputBean)itemWebBean).getValue(pageContext);
           //((OAMessageLovInputBean)itemWebBean).setValue(pageContext, null);
          }
                     //OAMessageLovChoiceBean
                     else if ((itemWebBean instanceofOAMessageLovChoiceBean))
                     {
            valueStr = ((OAMessageLovChoiceBean)itemWebBean).getValue(pageContext);
                             //((OAMessageLovChoiceBean)itemWebBean).setValue(pageContext,null);
           }
         //OAMessageChoiceBean
          else if(itemWebBean instanceof OAMessageChoiceBean)
          {
                        valueStr = ((OAMessageChoiceBean)itemWebBean).getValue(pageContext);
           //((OAMessageChoiceBean)itemWebBean).setValue(pageContext, null);
          }
         //OAMessageDateFieldBean
          else if(itemWebBean instanceof OAMessageDateFieldBean)
          {                       
                        valueStr =((OAMessageDateFieldBean)itemWebBean).getValue(pageContext);
           //((OAMessageDateFieldBean)itemWebBean).setValue(pageContext, null);
          }
         //OAFormValueBean
          else if(itemWebBean instanceof OAFormValueBean)
          {
                        valueStr =((OAFormValueBean)itemWebBean).getValue(pageContext);
           //((OAFormValueBean)itemWebBean).setValue(pageContext, null);
          }
         //OAMessageCheckBoxBean
          else if (itemWebBeaninstanceof OAMessageCheckBoxBean)
          {
                       valueStr =((OAMessageCheckBoxBean)itemWebBean).getValue(pageContext);
           //((OAMessageCheckBoxBean)itemWebBean).setValue(pageContext, null);
          } else
          {
            thrownew OAException("Not Found the webBean");
          }
        }
                            if (null != valueStr) {
                                     value = valueStr.toString();
                            } else {
                                     value = "";
                            }
                            if (!isStrNull(value)) {
                                     searchMap.put(strWebBeanNames[i], value);
                            }
      }
    }
          return searchMap;
  }

//OAF对隐藏控件清空控件值(保证不刷新页面)
清空控件为button，并且绑定局部事件clearBtn
1、点击清空时触发事件clearBtn(清空请求里的值)
String[] clearBeanNames =
{ "testDateFrom", "testDateTo" };
CustomSearchUtil.resetWebBean(pageContext, webBean, clearBeanNames);//参考 动态控件值的获取
2、在button上写JS事件//参考 OAF注册JS事件
jsString.append("lovClearValue(document.DefaultFormName." + 
webBeanClearNames[i] + ");");

//processRequest方法初始化时，获取控件的值

  OAMessageDateFieldBean sendDate = 
           (OAMessageDateFieldBean)webBean.findChildRecursive("sendDate");
  String sendDates = null;
  Object obj =sendDate.getValue(pageContext);
  if(null!=obj){
       sendDates =obj.toString();
  }
Date date = new Date();

//要加pageContext，否则刷新页面，时间会一直是初始值

sendDate.setValue(pageContext, date);

4、OAF中注册JS事件

触发函数：changeBeanStatusJS(pageContext,webBean, "warehouse");
//效果:
//仓库过滤条件，若选择109北京卷烟厂,110天津卷烟厂,111高扬自营，则审核按钮不可见，
//"审核标记"默认为"审核"
public void changeBeanStatusJS(OAPageContextpageContext, 
                                                                           OAWebBean webBean, String beanName) {
         StringBuffer jsStr = new StringBuffer();
         jsStr.append(" function changeBeanStatusJS(){ ");

         //下拉框赋值(展示值):OAF下拉框对应Code值不是页面代码下拉框对应value值(其为加密形成的value值[一直变化的值])******
         jsStr.append("document.getElementById('formStatus').selectedIndex = 0;"); 

         //对于页面刷新时还存在的展示删除方式(textarea属性rows行从0开始cells列从0开始)
         jsStr.append(" var wareVal = document.getElementById('categoryLov').rows[1].cells[19].innerHTML = '';");
         jsStr.append(" var wareVal = document.getElementById('warehouseval').value;");
         jsStr.append(" wareVal =  wareVal.substring(0,3); "); //只取前三位，不知道formvalue这个控件什么原因字符串多了
         jsStr.append(" if( wareVal=='109' || wareVal=='110' ||wareVal=='111' ) { ");
         jsStr.append(" document.getElementById('Check').style.display ='none'; "); //设置不可见
         jsStr.append("document.getElementById('checkTag').options[1].selected=true; "); //选择1已审核
         jsStr.append(" document.getElementById('checkTag').disabled = true;");
         jsStr.append(" }else{ ");
         jsStr.append(" document.getElementById('Check').style.display = '';"); //设置可见 
         jsStr.append(" document.getElementById('checkTag').disabled =false; ");
         jsStr.append(" } ");
         jsStr.append(" } ");
         //此为加载页面时就添加JS函数
         //OABodyBean bodyBean = (OABodyBean)pageContext.getRootWebBean();
         OAMessageLovInputBean warehouse = 
                   (OAMessageLovInputBean)webBean.findChildRecursive(beanName);
         pageContext.putJavaScriptFunction("changeBeanStatusJS", 
                                                                                      jsStr.toString());
         if (warehouse != null) {
             //非空值触发JS函数
                   warehouse.setOnFocus("javascript:changeBeanStatusJS();");
         }
}
 
//SimpleDateFormat df = newSimpleDateFormat("yyyy-MM-dd");用此转换时间格式

5、控件messageLovChoice配置：

ID:wareHouseLovCho
External LOV:对应关联的RN
Picklist Display Attribute和Picklist Value Attribute配置
在对应的lovMap中
LOV Region Item:对应RN里的Code值
Return Item:上面的ID值
6、勾选框(messagecheckBox)设置问题:页面跳转手动设置
Initial Value设值一般为on
Checked Value设值一般为on 
在页面跳转前设值为：
//勾选框不进行设置，在勾选值去掉后，value有时还是为勾选时的值
Object value =pageContext.getParameter("checkFlag");
String flags = "";
if (value != null &&"on".equals(value.toString())) {
         flags = "on";
} else if (value == null) {
   flags = "";
}

7、单选框

两个messageRadioButton
设置为：Initial Value、Checked Value设置值相同1
        Unchecked Value设置值0
        另外一个相反
一个messageRadioGroup
不需要进行设置

------------------------------SubTabLayout问题-------------------------------

***需要根据条件进行Tab页的跳转时，需要在link绑定事件(否则不能正常跳转)***

OASubTabLayoutBean subTableLayOut=(OASubTabLayoutBean)webBean.findChildRecursive("SubTabRN");
    if (app_prop_code != null&& !("".equals(app_prop_code.trim())) && 
                   ("储运转烟厂高扬".equals(app_prop_code))) {
         subTableLayOut.hideSubTab(0, true);
         subTableLayOut.hideSubTab(2, false);
         subTableLayOut.hideSubTab(3, false);
         subTableLayOut.setSelectedIndex(pageContext, 2);
    } else {
         subTableLayOut.hideSubTab(0, false);
         subTableLayOut.hideSubTab(2, true);
         subTableLayOut.hideSubTab(3, true);
         subTableLayOut.setSelectedIndex(pageContext, 0);
    //此方法返回对应的Tab序列，可以放在processFormRequest中
         //多个按钮修改Tab展示第几个stackLayout方法
         //获取当前Tab位置(0,1,2)
    int i = subTableLayOut.getSelectedIndex(pageContext); 


Tab跳转：
1、processFormRequest方法中赋值：(value1...N)
  pageContext.putParameter("tabKey","valueN");
2、processRequest方法中拿值：   
   String tabKey =pageContext.getParameter("tabKey");
3、processRequest方法中比较： 
         //从查询tab跳转至明细tab
         if ("valueN".equals(tabKey)) {
                   subTabLayout.setSelectedIndex(pageContext, 1);
         }  

//把报表加载到特定Tab页下

  OAStackLayoutBean sumSubLayout = 
      (OAStackLayoutBean)webBean.findChildRecursive("SumSub");
 sumSubLayout.addIndexedChild(pdfElement); 
 //之前为pageContext.getPageLayoutBean().addIndexedChild(pdfElement);
(Tab中控制页面跳转时初始值赋值不改变：在对应的Link上绑定事件进行控制)

-------------------------------AM中问题---------------------------------

//AM中获取当前时间
this.getOADBTransaction().getCurrentDBDate();

//***OAF调用存储过程及从函数中取返回值***

    /**获取会计日期,//row.setAttribute只能是sql.Date类型
     * @param orgIds
     */
    private Date getCountDate(StringorgIds) {
        String sqlStr ="{? = call cux_common_yy_pkg.get_account_date(?)}";//函数(有返回值)
//或是                 
//String backStr = 
//" begin cux_inv_inv073_pkg.validate_sedaccount
//(p_account_date => :1, x_rs_flag => :2,x_rs_msg  => :3); end; ";(过程，通过OUT实现返回值)
        //String x_succ_flag= "";
        //String x_error_msg= "";
        CallableStatementproc = null;
        Date curDate = null;
        OADBTransaction tr =getOADBTransaction();
        proc =tr.createCallableStatement(sqlStr, 1);
        try {
            //注册返回类型
           proc.registerOutParameter(1, Types.DATE);
           //statement.registerOutParameter(2, Types.VARCHAR);
           //statement.registerOutParameter(3, Types.VARCHAR);
           proc.setString(2, orgIds);
           proc.execute(); //执行
                            //proc.executeQuery此为结果集ResultSet
           curDate = proc.getDate(1); //获取结果(必须在关闭前获取数据，关闭不能正常获取数据)
           //x_succ_flag = statement.getString(2);
           //x_error_msg = statement.getString(3);
           proc.close();
        } catch(SQLException e) {
            thrownew OAException("执行存储过程出现错误:" + sqlStr, OAException.ERROR);
        }
        return curDate;
    }

//VO中根据字段是否正负显示 盈亏
DECODE((SIGN(InventoryProfitlossDetEO.PROFITLOSSWEIGHT)),-1, '盘亏', '盘盈') AS PROFITLOSSDS  
//LOV对应RN的CO查询功能中有OR时需要加()
vo.setWhereClause(" ( ATTRIBUTE1 in('2','4') or code in ('104','106')) ");
//如再有输入数据，默认以AND连接ATTRIBUTE1in ('2','4') or code in ('104','106') AND[这样有问题]
/**查询条件时间格式两种*/
reportDate>=fnd_conc_date.string_to_date('2015-09-09')//即把字符串值转换为OAF认知的时间值
trunc(reportDate)<=to_date('2015-09-09','yyyy-MM-dd')//trunc(sysdate)返回今天的日期值

-------------------------------Table问题--------------------------------

//控制table显示的number格式

Formatter numForm = new OADecimalValidater("0.00", "0.00");
//OADateValidater dateForm = new OADateValidater("yyyy-MM-dd", "");
OAWebBean abl = webBean.findChildRecursive("weightPer");
if (null != abl){
if (abl instanceof OAMessageStyledTextBean) {
((OAMessageStyledTextBean)abl).setAttributeValue(ON_SUBMIT_VALIDATER_ATTR, 
numForm);
} else if (abl instanceof OAMessageTextInputBean) {
((OAMessageTextInputBean)abl).setAttributeValue(ON_SUBMIT_VALIDATER_ATTR, 
numForm);
}
} 

//Table：Total Value为true时总计字段上加格式：如千分位

1、MonWastageSumVO1为table名称
2、Totalloss对应table总计字段名称
3、bValues是赋给总计的值，具体格式要自己设置好后传过来
OATableBean table = 
         (OATableBean)webBean.findIndexedChildRecursive("MonWastageSumVO1");
OAWebBean abl =table.findIndexedChildRecursive("Totalloss");
//bValues：为格式化后的
if (null != abl){
         if (abl instanceof OAMessageStyledTextBean) {
                   ((OAMessageStyledTextBean)abl).setAttributeValue(TABULAR_FUNCTION_VALUE_ATTR, 
                                                                                                                                    bValues);
         } else if (abl instanceof OAMessageTextInputBean) {
                   ((OAMessageTextInputBean)abl).setAttributeValue(TABULAR_FUNCTION_VALUE_ATTR, 
                                                                                                                                   bValues);
         }
}                                                                                                                  

//***控制table显示一页显示条数***

if ("pageNumEvent".equals(event)) {//在对应下拉框设置事件
    String[] tableNames = {"BtnAccountTable" };//表格ID值***
         CommonUtils.setPageNumbers(pageContext, webBean, tableNames, 
                                                                    "pageNumChoice");
         //执行一次查询
         BtnAccountVOImpl vo = 
                   (BtnAccountVOImpl)am.findViewObject("BtnAccountVO1");
         if (vo.getFetchedRowCount() > 0) {
                   vo.executeQuery();
                   //显示缓存中总条数
                   vo.getRowCount();
         }
}       
//具体方法
public static void setPageNumbers(OAPageContextpageContext, OAWebBean webBean, 
                                                                 String[] tableNames, String pageNumChoice) {
         //默认20
         int num = 20;
         String pageNum = pageContext.getParameter(pageNumChoice);
         if (null != pageNum && !"".equals(pageNum.trim())) {
                   num = Integer.parseInt(pageNum);
         }
         if (null != tableNames) {
                   for (String tableName: tableNames) {
                            //获得Table控件***
                            OATableBean mainTable = 
                                     (OATableBean)webBean.findChildRecursive(tableName);
                            if (null != mainTable) {
                            //设置对应一页多少条数据***
                            mainTable.setNumberOfRowsDisplayed(num);
                            }
                   }
         }
}

//设置表格左右对齐

1、在表格VO中设置
decode(ProduceTobacooDetEO.CONSUMETYPE, 1,'left', 10, 'left', 'right') AS halign
2、在字段上层加rowLayout(ID值为'region33')
3、在初始化方法processRequest里加
OARowLayoutBean rowLB = (OARowLayoutBean)webBean.findIndexedChildRecursive("region33");
if(null!=rowLB){
 rowLB.setAttributeValue(UIConstants.H_ALIGN_ATTR,newOADataBoundValueViewObject(rowLB,"Halign"));
}

-------------------------------EO问题--------------------------------------         

-----在EO中注意是否有ROWID字段，否则在建VO时一直会有报错-----
if (value != null &&value.toString().matches("^[0-9]*\\.[0-9]{6,99}$")) {
         Number value = new Number();(得导入import oracle.jbo.domain.Number;才不会报错在OAF中，在MyEclipse不行)
         String str = value.toString().substring(0, value.toString().split("\\.")[0].length()+ 6);//加个判断若输入大于5位小数保留5位小数
         value = value.subtract(value).add(Double.parseDouble(str));  

-------------------------------PVO问题--------------------------------------      

-----根据条件隐藏控件三步走PVO*****
//初始化
am.invokeMethod("init"); //初始化PVO
public void init() {
         OAViewObject appPropsVO =(OAViewObject)findViewObject("SumInvPLPVO1");
         if (appPropsVO != null) {
                   if (appPropsVO.getFetchedRowCount() == 0) {
                            appPropsVO.setMaxFetchSize(0);
                            appPropsVO.executeQuery();
                            appPropsVO.insertRow(appPropsVO.createRow());
                            OARow row = (OARow)appPropsVO.first();
                            row.setAttribute("RowKey", new Integer(1));
                   }
         }
}
//一定条件后
btnValue = "1,2,3,4,5";
Serializable[] paraBtn = { btnValue };
am.invokeMethod("initBtn", paraBtn);
public void initBtn(String btnValue) {
         String[] btns = btnValue.split(",");
         for (int i = 0, k = btns.length; i < k; i++) {
                   OAViewObject vo =(OAViewObject)findViewObject("SumInvPLPVO1");
                   OARow row = (OARow)vo.first();
                   if ("1".equals(btns[i])) {
                            row.setAttribute("makeSumRender",Boolean.TRUE);
                            continue;
                   } else if ("2".equals(btns[i])) {
                            row.setAttribute("cancelSumRender",Boolean.TRUE);
                            continue;
                   }
         }
}
Rendered上绑定：${oa.SumInvPLPVO1.cancelSumRender}

-------------------------------报表问题--------------------------------------

//报表展示(第一个方法里加载)
//把报表加载到特定Tab页下
OAStackLayoutBean sumSubLayout = 
         (OAStackLayoutBean)webBean.findChildRecursive("SumSub");
/**参数名称要和报表里参数一样*/
String[] paramsName ={"attr1","attr2","attr3","attr4"}
String[] paramsValues = {attr1,attr2,attr3,attr4}
//显示报表：参数传递FineReport的模板参数
//(1)
OAHTMLWebBean pdfElement = 
         (OAHTMLWebBean)createWebBean(pageContext, HTML_WEB_BEAN, null, 
                                                                            "IFRAME");
//(2)                                                                     
FineReportUtil.genFineReportIframe(pdfElement,"INV031", 
                                                                              paramsName, paramsValues, true);
//把报表加载到特定Tab页下
sumSubLayout.addIndexedChild(pdfElement);       
/**在一般页面加载
pageContext.getPageLayoutBean().addIndexedChild(pdfElement);
*/
/**把报表加载到特定的header下*/
//根据ID值获取header控件
OAHeaderBean header = 
         (OAHeaderBean)webBean.findChildRecursive("reportHdr");
//把报表加载到特定header页下
header.addIndexedChild(pdfElement);
