一、摘要
实现OAF修改功能Update
二、案例
需求:实现修改功能
1. 建立Update按钮的连接
2. 设定触发事件为FireAction
3. 在SearchInvoiceCO.java中添加如下方法
4. 建立UpdateInvoicePG
5. 在UpdateInvoiceCO.java中添加如下方法
6. 在InvoiceAM中添加如下方法
7. 在InvocieUpdateVO中添加如下方法
8. 在UpdateInvoiceCO.java中添加如下方法
9. 在InvoiceAM中添加如下方法
三、案例实现
1. 建立Update的连接
2. 设定触发事件为FireAction
3. 在SearchInvoiceCO.java中添加如下方法
1 public void processFormRequest(OAPageContext pageContext,OAWebBean webBean) { 2
3 super.processFormRequest(pageContext, webBean); 4
5 /**按下更改发票Button,触发AM中的AmUpdateInvocie方法**/
6
7 if ("update".equals(pageContext.getParameter(EVENT_PARAM))) { 8
9 OAApplicationModule am = pageContext.getApplicationModule(webBean); 10
11 pageContext.setForwardURL("OA.jsp?page=/oracle/apps/bxj/ap/invoice/webui/UpdateInvoicePG", 12
13 null, 14
15 OAWebBeanConstants.KEEP_MENU_CONTEXT, 16
17 null, 18
19 null, 20
21 true, 22
23 OAWebBeanConstants.ADD_BREAD_CRUMB_NO, 24
25 OAWebBeanConstants.IGNORE_MESSAGES); 26
27 } 28
29 }
4. 建立UpdateInvoicePG
5. 在UpdateInvoiceCO.java中添加如下方法
1 public void processRequest(OAPageContext pageContext, OAWebBean webBean) { 2
3 super.processRequest(pageContext, webBean); 4
5 /**从SearchInvoice调转至UpdateInvoice,对修改发票页面初始化**/
6
7 String InvoiceId = pageContext.getParameter("InvoiceId"); 8
9 if (!pageContext.isBackNavigationFired(false)) { 10
11 TransactionUnitHelper.startTransactionUnit(pageContext,"UpdateInvoiceTxn"); 12
13 if (!pageContext.isFormSubmission()) { 14
15 Serializable[] params = { InvoiceId }; 16
17 OAApplicationModule am = pageContext.getApplicationModule(webBean); 18
19 am.invokeMethod("AmInitUpdateInvoice",params); 20
21 } 22
23 } else { 24
25 if (!TransactionUnitHelper.isTransactionUnitInProgress(pageContext,"UpdateInvoiceTxn",true)) { 26
27 OADialogPage dialogPage = new OADialogPage(NAVIGATION_ERROR); 28
29 pageContext.redirectToDialogPage(dialogPage); 30
31 } 32
33 } 34
35 }
6. 在InvoiceAM中添加如下方法
1 /**显示Invoice 明细页面**/
2
3 public void AmShowInvoice(String InvoiceId){ 4
5 InvoiceDetailVOImpl vo = getInvoiceDetailVO1(); 6
7 if (vo == null) { 8
9 MessageToken[] errtokens = {new MessageToken("OBJECT_NAME","InvoiceDetailVO1")}; 10
11 throw new OAException("AK","FWK_TBX_OBJECT_NOT_FOUND",errtokens); 12
13 } 14
15 vo.VoShowInvoice(InvoiceId); 16
17 }
7. 在InvocieUpdateVO中添加如下方法
1 /**从SearchInvoice页面跳转至UpdateInvoice页面,实现自动查询**/
2
3 public void VoShowInvoice(String InvoiceId) { 4
5 if ((InvoiceId != null) & (!("".equals(InvoiceId.trim())))) { 6
7 Number Invoice_Id = null; 8
9 try { 10
11 Invoice_Id = new Number(InvoiceId); 12
13 } catch (Exception e) { 14
15 throw new OAException("CUX", "CUX_INVOICE_INVALID_NOTIFY_ID"); 16
17 } 18
19 setWhereClause("INVOICE_ID = :1"); 20
21 setWhereClauseParams(null); 22
23 setWhereClauseParam(0, Invoice_Id); 24
25 executeQuery(); 26
27 } 28
29 }
8. 在UpdateInvoiceCO.java中添加如下方法
1 public void processFormRequest(OAPageContext pageContext,OAWebBean webBean) { 2
3 super.processFormRequest(pageContext, webBean); 4
5 /**按下确定Button后,调用修改Invoice的AM 方法**/
6
7 OAApplicationModule am = pageContext.getApplicationModule(webBean); 8
9 if (pageContext.getParameter("Apply") != null) { 10
11 OAViewObject vo = (OAViewObject)am.findViewObject("UpdateInvoiceVO1"); 12
13 am.invokeMethod("AmUpdateApply", null); 14
15 TransactionUnitHelper.endTransactionUnit(pageContext,"UpdateInvoiceTxn"); 16
17 pageContext.forwardImmediately("OA.jsp?page=/oracle/apps/bxj/ap/invoice/webui/SearchInvoicePG", 18
19 null, 20
21 OAWebBeanConstants.KEEP_MENU_CONTEXT, 22
23 null, null, true, 24
25 OAWebBeanConstants.ADD_BREAD_CRUMB_NO); 26
27 } else if (pageContext.getParameter("Cancel") != null) { 28
29 am.invokeMethod("AmCreateRollback", null); 30
31 TransactionUnitHelper.endTransactionUnit(pageContext, "CreateInvoiceTxn"); 32
33 pageContext.forwardImmediately("OA.jsp?page=/oracle/apps/bxj/ap/invoice/webui/SearchInvoicePG", null, 34
35 OAWebBeanConstants.KEEP_MENU_CONTEXT, 36
37 null,null,true, 38
39 OAWebBeanConstants.ADD_BREAD_CRUMB_NO); 40
41 } 42
43 }
9. 在InvoiceAM中添加如下方法
1 /**修改Invoice,将资料做Commit**/
2
3 public void AmUpdateApply() { 4
5 getTransaction().commit(); 6
7 }
