I am loading an external swf into an component. It loads everything fine and I can see buttons working in the swf, but I can't seem to figure out how to add children to this swf from the core mxml file. I have tried tracing out all the children of the image component but can't find where or how to do this.

This is the image component:

<Image id="image" mask="{ maskCanvas }" source="{ _source }" mouseDown="image.startDrag()" visible="{ _source != null &amp;&amp; image.percentLoaded == 100 }"
        showEffect="{ fadeInEffect }" complete="imageComplete()" doubleClickEnabled="true" doubleClick="onDoubleClick()" />

And in my AS, I am trying to do something like this:

myComponent.image.addChild("myMC");

But i either don;t see the clip or there I get an error about not being able to add the child to a ui component.
