Tried the hotfix and didn't work. Also tried listening to the event on stage like you specified, but again that gets fired after the error.
Interesting you mention the problem with scrollbars, because that's what it seems like the problem is here too. The FM is looking for the parent of VScrollBar (or HSCrollBar) in a VBox for example and that's what throws the error. It's a shame that the hotfix didn't work, i was really enthusiastic. Other ideas? Mark On 5/23/07, Alex Harui <[EMAIL PROTECTED]> wrote:
The hotfix fixed a problem where scrollbars were accidentally getting focus. In theory in your creationComplete handler, you should be able to do: systemManager.stage.addEventListener(FocusEvent.KEY_FOCUS_CHANGE, focusChangeHandler); and start seeing traces. ------------------------------ *From:* flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] *On Behalf Of *Mark Kornfilt *Sent:* Wednesday, May 23, 2007 10:13 AM *To:* flexcoders@yahoogroups.com *Subject:* Re: [flexcoders] Tabbing bug - disabling tabbing in the application I have tried adding the listener to the main application, and to an individual text input, but i can't catch it. I have tried listening both with and without useCapture (therefore attaching in an mxml tag and also manually on creation complete -- not both at the same time of course). the handler is just a dumb handler but I can still provide it: private function focusChangeHandler(event : Event) : void { trace("focus change"); } I would be interested to know how you were able to shut down the FM. We are not running 2.0.1 hotfix, because we don't use any DataGrid and I didn't see any fix worth making the change for now. Is there a fix that wasn't described in the hotfix kb?

The child it's looking for seems to be quite often a VScrollBar and the parent a VBox. I'll try the keyFocusChange today.

The error is the following: ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller. at flash.display::DisplayObjectContainer/getChildIndex() at mx.core::Container/getChildIndex ()[C:\dev\flex_201_gmc\sdk\frameworks\mx\core\Container.as:2442] at fl.managers::FocusManager/::getChildIndex() at fl.managers::FocusManager/::sortByDepth() at Array$/Array::_sort() at Array/http://adobe.com/AS3/2006/builtin::sort() at fl.managers::FocusManager/::sortFocusableObjects() at fl.managers::FocusManager/::keyDownHandler() I am currently unable to narrow down the problem to a specific component, so until I find a better solution, I would like to disable tabbing globally in the application. It's impossible to provide an exhaustive list of things I've tried in order to achieve that result, but I've been unable to block the tab keydown event from getting to the FocusManager. I have tried listening to the keydown event everywhere (also using useCapture = true) in the application, from the root component to the fields where the user can actually press tab, but nothing works. Does anybody have a quick fix to disable tabbing? Thanks, Mark
