I tried with calculateDropIndex, but this function returns
the index where I should insert the item in the drop target.
For instance, if you drag Node 1.1.2 over Node 1.1.1, the
calculateDropIndex would return 0 because that's the drop index I
should insert Node 1.1.1 in Branch 1.1...
What i'm looking for is a function that returns me the item
i'm rolling over.
It is working perfectly in Beta 2 with the following code:
var lDropRowIndex:int = lTree.getDropRowIndex( iEvent );
bject = lTree.getNodeDisplayedAt( lDropRowIndex );
