[RESOLVED] MXML Mask Issue

I've run into a slight problem that I am not seeing the answer to. I'm trying to apply a mask (a canvas) to another canvas. But for some reason the mask is not doing it's job.

Below is my code:

Code:

---

        <mx:Canvas id="masker"
                width="300" height="400"
                visible="false" backgroundColor="#000000" />
               
        <mx:Canvas id="target"
                width="400" height="700"
                mask="{masker}"
                backgroundColor="#FF0000">
                <mx:Canvas backgroundColor="#00FF00"
                        width="50%" height="50%"
                        right="0" bottom="0" />
                <mx:Canvas backgroundColor="#00FF00"
                        width="50%" height="50%"  x="0" y="0"/>
        </mx:Canvas>

---

Any help on this would be greatly appreciated.

Found issue. Had an actionscript piece of code that was changing the mask value of the canvas.
