MXML composite container initialization error

I'm getting an odd error from my composite canvas component:

 An ActionScript error has occurred:
  Error: null
at mx.core::Container/initialize()[C:\autobuild\galaga\frameworks\projects\framework\src\mx\core\Container.as:2560]
at -REMOVED THIS FOR STACK OVERFLOW-.view::EditableCanvas/initialize()[.../view/EditableCanvas
    ....

It seems to be related to the fact that my composite component has a child and I'm trying to add one in the place I'm using the component. So how can I do this correctly?

Component code looks like this (EditableCanvas.mxml):

<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script>
<mx:Image id="editTextImage"
            source="@Embed('/../assets/icons/small/edit.png')"/>
</mx:Canvas>

The code that is using the code looks like this:

<view:EditableCanvas
            width="290" 
            height="120" 
            backgroundColor="#FFFFFF" 
            horizontalScrollPolicy="off" 
            borderStyle="solid" 
            cornerRadius="3">
            <mx:Text id="textContentBox" width="270" fontFamily="nautics" fontSize="12" text="{_text}"/>
</view:EditableCanvas>

So I found the solution all by my own from Adobe Flex 3 Help:

If you include child tags of the root container tag in an MXML component file, you cannot add child tags when you use the component as a custom tag in another MXML file. If you define an empty container in an MXML file, you can add child tags when you use the component as a custom tag.

The way to have child elements in a composite component (that also accepts childs from custom tag) is to add them after creationComplete in as3.

Have you tried not binding to the init() function, and instead just having creationComplete="init()" ?
