Another Tricky Flex 2 Error

September 14th, 2007 | Category: Actionscript 3.0, Flex 2.0, Flash, Left-Brain, Solution, Daily

Ran into another Flex 2 error the other day that’s again not crystal clear about what it’s trying to tell you. This one is:

Invalid Embed directive in stylesheet - can’t resolve source ‘Embed(source = “assets/my_picture.png”)’

Here’s the source:

1
2
3
4
5
6

       <mx:style>
		.customVideoTree
		{
			defaultLeafIcon:Embed(source="assets/ds-qhv-film-icon.png");
		}
	</mx:style>

This one is pretty clear in hindsight, but care to guess what that error up there means to say? My initial thinking was that it was a syntax error with the Embed directive, but nope, the $25,000 answer is. . .

file not found

Now you know what can’t resolve source means, which of course makes perfect sense now. . .but sure tripped my up on the spot.

Flex 2 Strange Error

September 08th, 2007 | Category: Actionscript 3.0, Flex 2.0, Flash, Left-Brain, Solution, Daily

I ran into an error while working on a Flex2 application this morning. The error made zero sense in the context, and I wasn’t able to find anything that explained it (reasonably) via google. So, here’s what I found the hard way :

The error was:

[RPC Fault faultString=”Error #2070: Security sandbox violation: caller cannot access Stage owned by .” faultCode=”Client.CouldNotDecode” faultDetail=”null”]

Here’s some sample code that will replicate the error:

<mx:application xmlns:mx="http://www.adobe.com/2006/mxml" width="800" height="600">
	initialize="e4xService.send()"&gt;
 
	<mx:script>
		<!--[CDATA[
			public function handleHttpResult(event:Event):void
			{
 
			}
		]]-->
	</mx:script>
 
	<mx:httpservice id="e4xService" url="assets/videos.xml" result="handleHttpResult(event)">
</mx:httpservice>
</mx:application>

And here’s some example XML for the “assets/videos.xml” file:

Line 25 had some poorly formatted XML; “<application label=”Desktop Application”/>” (Closing the tag while it had children). This was my problem.

So, the short answer is: If you see this problem and you’re remotely loading an xml file, go over your xml with a fine toothed comb. The text of the error doesn’t make a lot of sense in context.

Hope that helps!
