> I gotta feeling Matt is going to tell me to go wish :) Yep :-) If you don't find something it might be worth contacting support, I know I don't really have time right now to investigate. Did you try setting selectedDate to undefined before destroying it? If it seems to be selecting the date that's the problem maybe it would clean it up?

It appears that if I select a date programmatically and then delete the component memory usage starts to creep up and is seemingly never garbage collected. The sample code below when run on my machine uses up a delta of ~50M between when the app is first loaded and after 100 iterations of this sequence. Additionally after 100 iterations the Internet Explorer process is chewing up ~20% of my CPU while the app is supposedly idling. Has anyone else run into this issue and perhaps found a workaround? I gotta feeling Matt is going to tell me to go wish :) Cheers, Paul. <?xml version="1.0" encoding="iso-8859-1"?> <mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"; load="myLoad()" > <mx:Script> <![CDATA[ var counter:Number; var intervalId1:Number; var intervalId2:Number; var date:Date; function destroy():Void { clearInterval(intervalId2); viewStack.destroyChildAt(0); counter = counter + 1; if (counter == 100) { clearInterval(intervalId1); } } function create():Void { trace("date= " + date); var dateField = viewStack.createChild(mx.controls.DateField, undefined); dateField.selectedDate = date; intervalId2= setInterval(this, "destroy", 2000); } function myLoad():Void { counter =0; date = new Date(); } function startIterations():Void { intervalId1= setInterval(this, "create", 3000); } function stopIterations():Void { clearInterval(intervalId1); } ]]> </mx:Script> <mx:VBox> <mx:ViewStack id="viewStack" /> <mx:Button label="start iterations" click="startIterations()"/> <mx:Button label="stop iterations" click="stopIterations()"/> <mx:Label text="{counter}" /> </mx:VBox> </mx:Application> ~~------- This e-mail may contain confidential information.
