Hi there,


The following problem comes to me and I can't create a simple test for reproduce the bug :






The current DisplayObject :


	horizontalScrollPolicy="off" verticalScrollPolicy="off">

	angle='45' blurX='4' blurY='4' distance='4' alpha='0.4' color='#000000' knockout='false' quality='1'
	strength='1' inner='false' hideObject='false'/>

				/* Here is my image, the canvas content auto ajust */
				/* a replacement with an mx:Button don't change anything */


Thanks in advance

It'd be SUPER helpful if you'd zip up a simplified Flex project that clearly demonstrates the issue and send it directly to me via e-mail or private message. When I pasted your code into Flex, it kept complaining "Initializer for property 'states' is not allowed here". I've got a lot on my plate at the moment and don't have much time to try building something that reproduces the problem (TransformManager seems to work great for me and nobody else has complained about a similar issue), so your help would be greatly appreciated.

Yep, looks like yet another bug in the Flex framework. It doesn't accurately perform globalToLocal() on a canvas with a border (it offsets things by the thickness of the border). You can see proof with this simple MXML:


<br>			import mx.containers.Canvas;<br><br>			public function doMain():void {<br><br>				var redReg:Point = red.parent.globalToLocal(red.localToGlobal(new Point(0, 0))); //just translates the origin of the red box into the coordinate space of its parent where we'll position the green box.<br><br>				//now position the green box directly over the red box (you'll see that it's actually offset by however thick the border of the parent is (which is a bug in Flex)<br>				green.x = redReg.x;<br>				green.y = redReg.y;<br><br>			} <br>		]]><br>


If you've got any ideas on how to elegantly work around the Flex bug, let me know. I'm not interested in littering my code with a bunch of conditional logic to accommodate a Canvas border, though, especially because it seems to be an obvious bug in the framework that Adobe will hopefully fix on the next rev of Flex.
