Unbound ItemRenderer

Hello,

Is there a safe way to be notified that an item renderer used to render items in a tiled list (either horizontal or vertical list) is not used anymore (for instance when switching from a state in which the data provider contains one or more items to a state in which the data provider does not contain any item).

Using Flex 3.0.x, I noticed that none of the following approaches works :

• Intercepting the dataChange event - This event is not called when a previously bound item renderer is no longer used
• Intercepting the flex.event.Event.REMOVE event - This event seems not to be called when the item renderer is removed from its parent
• Intercepting the flash.event.Event.REMOVED event of the item renderer parent. Same. Not called.

Any idea ?

Thanks in advance - Regards

Unbound ItemRenderer

I finally found a workaround consisting in intercepting the call to visible = false made by ListBase.addToFreeItemRenderers.

It is not bullet proof but may help in some situations :

public override function set visible( value: Boolean ): void {

super.visible = value;

if ( value == false ) {

?// doSomething

}

}
