You should take a look at this thread:
Hi, Thanks for the response.
I will try and detail my issue further:
Before when working with a TileList I would add a list event to the list (not the itemrenderer) which seemed to be a much cleaner way of capturing these item events that dispatching them individually from each item in the list.
If I add RollOver && RollOut on the Spark List component it refers to the list and not each item (children) of the component.
It appears looking at the link you sent me that you would now need to add the EventListener to the itemrenderer to get the events for the items/children of the list?
Let me know
That is correct, in spark you will need to add the event listeners to the ItemRenderer.
