Which version of Flex are you using? I think we fixed a focusrect issue recently.

This in turn has 59 references ...so after spending long time could not find the culprit yet. Made some INTERESTING observations: The problem happens only if the editor is TextInput, but does not happen with CheckBoxEditor and ComboBoxEditors. My TextInputEditor is subclass of TextInput and implements IFactory. As you said, I looked at the references of itemEditor itself. All are circular except HaloFocusRect and UITextField. There are lot of circular references held by Functions like 'keyUpHandler', 'keyDownHandler', 'focusInHandler', 'focusOutHandler', 'removedHandler', 'addedHandler', 'changeHandler' etc. --- In flexcoders@yahoogroups.com<mailto:flexcoders%40yahoogroups.com>, Alex Harui <aha...@...> wrote: > > The next step is to chase all 9 references to see if they are circular > (eventually end up back at Panel_A).
