Object doesn't look up scope tree for variables

I have a simple object defined by an object literal, and have a couple functions assigned to this object. Inside the functions, I try to access global variables, and it only gets undefined. The Flex debugger tells me the variables are just right up the scope tree.

Yes, I know I can access Thing by using 'this', that doesn't solve my scope issue though.

Project Flex Compiler Settings: Flex SDK 3.4, Require Flash Player 10.x.

Example:

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="Thing.bling();">

    <mx:Script>
        <![CDATA[
            var Thing:Object = {
                doStuff: function():void {
                    trace(blah); //blah is undefined
                },
                bling: function():void {
                    Thing.doStuff(); //Thing is undefined
                },

            };
        ]]>
    </mx:Script>

    <mx:Panel id="blah">

    </mx:Panel>
</mx:Application>

try

            var Thing:Object;
            Thing = {
                    doStuff: function():void {
                            trace(blah); //blah is undefined
                    },
                    bling: function():void {
                            Thing.doStuff(); //Thing is undefined
                    },

            };

just a guess ... but i experienced a lot of problems where this was neccessary ... too drunk and to tired to try out whether this solves the problem ... but for you, it should be just the beginning of the evening/night ... :D

I'm not sure what your trouble is, but I cut and paste your exact code into a new Flex project and despite a simple syntax error (extra trailing comma in the Thing declaration) it traced what I would expect:

Test0.blah

(Given that my project name is Test and the panel blah is the first object).

I used Flex 3.3 then tried Flex 3 both on Flash Player 10,0,22,87

edit:
I can reproduce now if I alter the project properties by following the instructions in the comments:
Flex Builder -> Properties -> Flex Compiler -> Require Flash Player Version -> 10.0.0

With this setting the behaviour does not appear in Flex 3.0 but does appear in 3.2, 3.3 and 3.4.

I suggest this is a bug and you should find a way to work around it.
