I wanted to raise awareness of this bug in the SDK: https://issues.apache.org/jira/browse/FLEX-33747
I have personally experienced this bug many times. An error occurs during layout validation and my Flex application becomes unusable. This is because other components do not respond to user interaction, and consequently execution seems to stop. I understand that errors that would present this problem should be fixed, but in my opinion the mantra of 'fail gracefully' should be respected, and resolving this issue would be hugely beneficial for the stability of Flex in general. If you have experienced runtime errors in your app and other components stop responding, then it is quite likely that fixing this bug will ensure your application remains responsive. If you are interested please vote this ticket up. I would like it fixed but like Mihai (the reporter) I really don't know enough to do more than a hackey monkey patch on LayoutManager. Marcus
