I get this error when I use the signalCommandMap

ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
    at flash.display::DisplayObjectContainer/getChildIndex()
    at mx.managers::SystemManager/getChildIndex()[E:\dev\hero_private\frameworks\projects\framework\src\mx\managers\SystemManager.as:1829]

    at mx.managers::SystemManager/mouseEventHandler()[E:\dev\hero_private\frameworks\projects\framework\src\mx\managers\SystemManager.as:2924]

It happens when I click in the flash.

I dont understand it. I have a fairly simple project. As you can see:

<?xml version="1.0" encoding="utf-8"?>
    <main:Main
    xmlns:fx="http://ns.adobe.com/mxml/2009"
    xmlns:mx="library://ns.adobe.com/flex/mx"
    xmlns:s="library://ns.adobe.com/flex/spark"
    xmlns:context="com.whatever.*"
    xmlns:main="com.whatever..*"
    >
    <fx:Declarations>
        <context:GameContext contextView="{this}"/>
    </fx:Declarations>
    <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx"
               >
        <s:Group>
        </s:Group>
    </s:Application>
</main:Main>

-

public class GameContext extends SignalContext
{
    override public function startup():void
    {
        var startupSignal:ApplicationStartedSignal = new ApplicationStartedSignal();
        signalCommandMap.mapSignal( startupSignal, PrepModelCommand, true );
    }
}

If I coment this line out the problem stops:

`signalCommandMap.mapSignal( startupSignal, PrepModelCommand, true );`

   Hi Christen,

   I'm afraid I don't use flex, but I've got a few thoughts that might help you to figure it out:

   1) It looks to me like something that is not a DisplayObject, or is not added to the stage, is being indexed on a DisplayObjectContainer.

   2) This is happening in response to your mouse event.

   You'd probably figured that much out...

   So - what's going on in that PrepModelCommand? Is it possible that somewhere you've got something being fired with a faulty 'clone' method, so that the clone function returns a MouseEvent when it should be a ModelEvent or similar?

   What does ApplicationStartedSignal extend? Is it a pure Signal or a NativeSignal?

   Thanks that's good suggestions.
   I have solved it by removing the

   ` <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

              xmlns:s="library://ns.adobe.com/flex/spark" 
              xmlns:mx="library://ns.adobe.com/flex/mx"
              >
   

   `

   I dident need it since the main class extends the application. I guess this messed it up. And properbly have something to do with what you wrote in 1). Something there was added thats was not a DisplayObject but an application.

   Thanks :)

   Phew! Yes - I guess spark and mx were bothering each other. I'm glad you got it fixed - I'll close this now, feel free to open new threads for anything else that you need help with.
