  1. I think I have possibly found a bug in the TransformManager class to do with selecting items. Please note I think this bug would be unlikely to occur if you were selecting/deselecting items using the mouse. I am probably only seeing it because I am supporting undo/redo operations in my application, so I am changing the selection programatically based on the history of user interactions. The bug: When setting the selection to be two items, and then setting the selection to be one (different) item, only one of the initially selected items is deselected. E.g. transformManager.selectItems( [ redItem, greenItem ] ); // returns transformItems for redItem, greenItem trace( transformManager.selectedItems ); transformManager.selectItems( [ blueItem ] ); // returns transformItems for redItem, blueItem. This is wrong! it should just be blueItem. trace( transformManager.selectedItems ); I believe the problem is a loop (line 1126) in the selectItems() method. It is iterating over the _selectedItems array, but I suspect the length of the array can be modified during an iteration, prematurely exiting the loop before all items are iterated over. I have seemingly fixed this behaviour by iterating over a copy of the _selectedItems array instead: e.g. var selectedItems : Array = _selectedItems.slice(); // ... iterate over copy instead Can anyone confirm that this is happening or am I misunderstanding something here?
