SDK 2.0 - Missing sample code for MaskGroup

Hi,

Haven’t gone that deep into the SDK 2.0. I was looking at the MaskGroup node class. I thought i could come up with a sample of my own but got an error.

Ok so this is my XML component file:

<?xml version="1.0" encoding="UTF-8"?>
<!--********** Copyright 2015 Roku Corp.  All Rights Reserved. **********-->
<component name="rectangleexample" extends="Scene">
   <script type="text/brightscript"><![CDATA[sub init()
  m.top.setFocus(true)
end sub]]></script>
   <children>
      <MaskGroup maskUri="pkg:/images/mask.png">
         <Rectangle id="testRectangle" color="0xFF0000FF" width="1280" height="60" translation="[0,0]" />
      </MaskGroup>
   </children>
</component>

I then proceeded to run the sample code and got this error.

=================================================================
Error creating XML component rectangleexample
– Error setting the “maskUri” field of a “MaskGroup” node
– Error found at line 8 of file pkg:/components/rectangle.xml

What gives?

Thanks.
