dynamic id for component?

[machmila]

I'm using a repeater to create several textInputs on the stage. I'd like to
assign each textInput a unique ID but I keep getting an error msg with my
formatting. Is this possible? The error I get is
'['autoCompleteMgr_'+catRepeater.currentItem.catID] is not a valid identifier'

<mx:TextInput id="{'autoCompleteMgr_'+catRepeater.currentItem.ca tID}"
width="300" themeColor="#F85F02"/>

Thanks!

One way you can do this is if you just give it an id, each individual element
can be accessed by treating that id as an array. Not exactly giving it a
completely dynamic id, but should be able to do everything using the array

<mx:Script>
<![CDATA[
public var repeaterData:Array = [10,20,30,40];
public function changeLabelText():void{
for(var i:int;i<repeaterData.length;i++){
myLabel[i].text=Math.random();
}
}
]]>
</mx:Script>
<mx:VBox>
<mx:Repeater id="myRepeater" dataProvider="{repeaterData}">
<mx:Label id="myLabel" text="{myRepeater.currentItem}"/>
</mx:Repeater>

<mx:Button click="changeLabelText()"/>
</mx:VBox>
