Hi,
I know this problem, happened to me once.
This is a known issue that won't be fixed by Adobe.
It usually happens when you try to scroll - the data is presented in
a wrong way.
But it has a solution.
Add an event listener for FlexEvent.DataChange in your itemRenderer.
In the listener function do your code again.
for instance if i have an inline item renderer that presents a
property named currentConcurrentCalls, i need to add an event
listener for the dataChange event and render it again there :
<mx:itemRenderer>
<mx:Component>
<mx:HBox width="100%" creationComplete="doInit()">
<mx:Script>
<![CDATA[
import mx.events.FlexEvent;
import mx.resources.ResourceBundle;
[ResourceBundle("hostlynx")]
private static const _rb:ResourceBundle;
[Bindable]
private var strMaxConcurrentCalls:String;
private function doInit():void{
if(data!=null && data.entityObject
["currentConcurrentCalls"] != null){
strMaxConcurrentCalls =
data.entityObject.currentConcurrentCalls;
}
addEventListener(FlexEvent.DATA_CHANGE,dataChange);
}
private function dataChange(event:FlexEvent):void{
if(data!=null && data.entityObject
["currentConcurrentCalls"] != null){
strMaxConcurrentCalls =
data.entityObject.currentConcurrentCalls;
}
}
]]>
</mx:Script>
<mx:Text id="txtCurrentCalls" text="{strMaxConcurrentCalls}"
styleName="dataGridText"/>
</mx:HBox>
</mx:Component>
</mx:itemRenderer>
Hope it helps,
Yossi
