Alex, Thanks very much for responding, however, I've figured it out.
I was adding my control bar as the last child in the constructor of my class, which subclasses TitleWindow. That triggered a call to Panel.createComponentsFromDescriptors(). That called Panel.setControlBar(myControlBar) as it should, and removed the controlBar from the container's regular child list and added it to the rawChildren. Since this happens in the constructor, my class is not yet added to the display list. After my class instance is added to the display list, the Panel.createChildren() method gets called, which again calls createComponentsFromDescriptors(). This time, since the last container child was not a ControlBar, it calls setControlBar(null). The fix was to add the control bar as a child in my class's createChildren() method, after super.createChildren() has been called. This is a Flex bug, IMHO. ________________________________ From: Alex Harui <aha...@adobe.com> To: "flexcoders@yahoogroups.com" <flexcoders@yahoogroups.com> Sent: Monday, March 12, 2012 1:34 PM Subject: Re: [flexcoders] ControlBar not visible in Flex 4.6 Re: [flexcoders] ControlBar not visible in Flex 4.6 Post a small test case.
