I have a TileList in my application where each element is rendered by a custom ItemRenderer. Each element of the above TileList has another TileList in it which is rendered for the first time by initialize event.
The outer TileList's dataprovider is an ArrayList of VO's which are returned from the server side. There is an inner array in each of the elements of the above ArrayList which requires some processing to create another ArrayList which becomes the dataprovider for the inner TileList(s). I have a button on my UI clicking on which I change the dataprovider of the outer TileList to a new ArrayList(containing exact same type of elements as before but with different data). I could not find an easy way to re-render the inner TileList(s) based on the new dataprovider for the outer TileList. After searching the list, I found a reply from Matt on a similar problem where he instructed to override the set data method for the outer TileList & refresh the datprovider of inner TileList in the body of the overridden method. This part works perfectly. But if I try to dispatch a FlexEvent.DATA_CHANGE from the overriden set data method & put a dataChange handler on the outer TileList, the datachange handler doesn't get called. Is this a bug or expected behavior ? How do I receive the notification for dataChange event ? I was thinking of switching the dataProvider of the inner TileList in dataChange handler. Is this not the right way ? Thanks, Aejaz
