I'm having the exact same type of problem swapping containers in a TabNavigator using this type of command
main.setChildIndex(main.getChildAt(2),1); The behind code seems to choke on the getChildAt of the container. I had the some index problems on other things with this component and for that one found that using callLater solved part of it. Perhaps you could give that a try, failing that if you find a simple answer to your problem I d be interested in hearing about your solution. Ill do likewise if I find a solution to the current index problem. Anyway Frustrating to say the least. jason -----Message d'origine----- De : flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] la part de Ciarán Envoyé : jeudi 2 novembre 2006 14:29 À : flexcoders@yahoogroups.com Objet : [flexcoders] AddChild() Exceptions Hi All, I'm having a slight problem building a custom component. The basic idea is a combination of a primary image container, and a Tile() container providing a selection of images. When selected, each image would appear as a primary image. This sounds tediously simple. I'm implementing it upon the principle that a change event is broadcast when a setter is called, which has a registered listener that updates the component. It attempts to replace the at index 0. The annoying thing is that if I implement this from a vanilla perspective (blank text file), it works fine (making things much harder to debug since I can't reproduce the behaviour) - however in the context of the application I'm developing, it throws an exception: RangeError: Error #2006: The supplied index is out of bounds. at flash.display::DisplayObjectContainer/getChildAt() at mx.core::Container/getChildAt()[C:\dev\GMC\sdk\frameworks\mx\core\Container. as:2384] at mx.core::UIComponent/notifyStyleChangeInChildren()[C:\dev\GMC\sdk\frameworks \mx\core\UIComponent.as:7099] at mx.core::Container/mx.core:Container::commitProperties()[C:\dev\GMC\sdk\fram eworks\mx\core\Container.as:2680] at mx.core::UIComponent/validateProperties()[C:\dev\GMC\sdk\frameworks\mx\core\ UIComponent.as:5218] at mx.managers::LayoutManager/mx.managers:LayoutManager::validateProperties()[C :\dev\GMC\sdk\frameworks\mx\managers\LayoutManager.as:517] at mx.managers::LayoutManager/mx.managers:LayoutManager::doPhasedInstantiation( )[C:\dev\GMC\sdk\frameworks\mx\managers\LayoutManager.as:628] at Function/http://adobe.com/AS3/2006/builtin::apply() at mx.core::UIComponent/mx.core:UIComponent::callLaterDispatcher2()[C:\dev\GMC\ sdk\frameworks\mx\core\UIComponent.as:7789] at mx.core::UIComponent/mx.core:UIComponent::callLaterDispatcher()[C:\dev\GMC\s dk\frameworks\mx\core\UIComponent.as:7732] This happens when the addChildAt() method gets called. Without divulging context, is there any obvious reason why I'm getting this exception? I've been battling this for hours now and it won't yield. If I'm not doing something incredibly stupid that would cause this, please let me know. Intuitively, it seems like the addChild() is triggering something at the wrong moment in time, giving something similar to an "Array out of bounds" as it looks for stuff to render. I understand most of the trace atomically speaking, but on the whole I have no idea how to remedy it. Also, I have an annoying problem with Flexbuilder. Breakpoints dont seem to work for me at all. I can't find any setting that implies this might've been turned off, so I'm not sure what to do about it. Perhaps find the checkbox that says "Don't work properly" and untick it. Any clues would be much appreciated =) Kind Regards, Ciarán -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com Yahoo!
