zz flex的DataGrid中使用ComboBox来实现

折腾一下午做这个功能，一直报错，包含在潜入在DataGridColumn里的Combox所使用的dataprovider绑定的变量，或是使用的event方法都不能被识别定义。

 

后来借鉴了下面这个例子，终于意识到是namespace的原因。修改后终于成功：

注意变量定义

[Bindable]
            public var availableMarketGroups:ArrayCollection;

 

引用时的namespace

Application.application.availableMarketGroups

嵌入的import语句

<mx:Script>
	<![CDATA[
			import mx.core.Application;
	]]>
</mx:Script> 

 

<mx:TitleWindow  width="514" height="445" layout="absolute" horizontalAlign="center" verticalAlign="middle" horizontalCenter="0" 
				 verticalCenter="-51" fontFamily="Arial" fontSize="12"  id="marketGroupAdminPanel" title="Market Group Administration"
				creationComplete="onGroupAdminWindowCreated(event)">						
		<mx:DataGrid  id="marketGroupList" allowMultipleSelection="true" horizontalScrollPolicy="auto" 
					  editable="true" verticalAlign="middle" 
					  name="Restricted Market and Group List"
					  textAlign="left" left="59" bottom="29" fontSize="12" 
					  fontFamily="Arial" right="68" 
					  verticalScrollPolicy="auto"
					  creationComplete="marketGroupListCreationComplete(event)" 
					  dataProvider="{getRestrictedMarketGroupInfosResult.lastResult}"
					  itemRollOver="lastRollOverIndex = event.rowIndex" 
					  contextMenu="{cmMarketGroupInfoListContextMenu}" top="44" tabIndex="4" >
		<mx:columns>
			<mx:DataGridColumn headerText="Market Name" dataField="marketName" editable="false"/>
			<mx:DataGridColumn headerText="Group Name" dataField="marketGroupName" editable="true"  itemEditor="{groupsDropDownComponent}">
				<mx:itemRenderer>
					<mx:Component id="groupsDropDownComponent">
						<mx:Box width="100%" height="100%">
							<mx:ComboBox dataProvider="{Application.application.availableMarketGroups}" labelField="marketGroupName">
								<mx:Script>
									<![CDATA[
										import mx.core.Application;
									]]>
								</mx:Script> 
							</mx:ComboBox>
						</mx:Box>
					</mx:Component>
				</mx:itemRenderer>
			</mx:DataGridColumn>
		</mx:columns>
	</mx:DataGrid>
	<mx:Button x="58" y="10" label="Create New Market Group" id="createMarketGroup" click="createMarketGroup_clickHandler(event)"/>
</mx:TitleWindow>
