Context Class: contextView property set twice with binding expression and throws error

[mfdj]

I was playing around with this HelloWorld example and I ran into a problem using Context inside the Declerations tag:

<fx:Declarations>
    <context:AppContext contextView="{this}" />
</fx:Declarations>

The probelm was that the contextView was getting set twice, which seems to cause Robotlegs 1.5.0 to freak out.

I'm using Flex 4.5.1 and Flash Builder 4.5.

I created some tests and it seems that any class declared in the Declarations tag will get properties with binding expressions set twice. Always, even if the binding is to a property of a basic type, like Number, who's value does not change at any point.

Weirdly, if the class is declared in the root-tag/DispalyList (in my case I created a test that extended UIComponent, so it could exist outside the Declarations tag) this double setting of the properties with binding expressions does not seem to occur.

I don't know if this is some weird configuration thing with my Flex setup, or if this is a 4.5 only issue… but I thought I'd bring it up as it was very frustrating because I liked the style of declaring the context as a tag, instead of using raw Actionscript.

My workaround is to patch it when extending Context — my AppContext.as has this:

override public function set contextView(value:DisplayObjectContainer):void
{
    if ( ! contextView ) super.contextView = value;
}

Basically it just ensures that if contextView has already been set, it doesn't get set again.

Let me know if I'm missing something.
