Hello,
After migrating an application from f2b3 to the final release of Flex
2 a new problem has emerged involving the FocusManager.
I use a FocusManager to focus on a TextInput when its parent becomes
visible. The text input does indeed take the focus and the component
responds to the keyboard without any problems. After this, however,
all mouse clicks in the application give the following error:
ArgumentError: Error #2025: The supplied DisplayObject must be a
child of the caller.
at flash.display::DisplayObjectContainer/getChildIndex()
at mx.managers::SystemManager/getChildIndex()
at mx.managers::SystemManager/::mouseDownHandler()
If I click "continue" in the error dialogue the same thing happens
when I next click the mouse.
However, if I click "dismiss all" the problem goes away altogether
and the application responds to clicks as it should.
After experimenting it appears to be the instantiation of the
FocusManager instance rather than calling its setFocus method that
causes the problem.
His is the function I call in response to show events on my component:
private function focusOnInput():void
{
var focusManager:FocusManager=new FocusManager(this);
focusManager.setFocus(searchTextInput);
}
Does any one know what's going on here or what I might be able to do
about it?
Thanks,
N51
