MXML composite canvas component initialization error
- by mkorpela
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" creationComplete="{init()}">
<mx:Script>
<![CDATA[
private var _editable:Boolean;
public function set editable(edit:Boolean):void {
_editable = edit;
}
private function init():void {
if(_editable){
addEventListener(MouseEvent.MOUSE_OVER, showEdit);
addEventListener(MouseEvent.MOUSE_OUT, hideEdit);
}
}
private function showEdit(event:Event):void {
editTextImage.visible = true;
}
private function hideEdit(event:Event):void {
editTextImage.visible = false;
}
]]>
</mx:Script>
<mx:Image id="editTextImage"
source="@Embed('/../assets/icons/small/process.png')"
click="{dispatchEvent(EditPoiEvent.text())}"
visible="false"/>
</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"
editable="{_editable}">
<mx:Text id="textContentBox" width="270" fontFamily="nautics" fontSize="12" text="{_text}"/>
</view:EditableCanvas>
