I've tried to find an answer to this that works in Flash Builder in the forums, but haven't yet - please feel free to redirect me if this is a repost! =)
My question is about casting within a binding tag. I was having problems casting from "Object" to a "Person" object (created in-house). Per threads about this written in 2007, this seems perfectly acceptable. Not so to my Flash Builder compiler. As a most basic test, I tried this:
[Bindable] public var test1:Object;
[Bindable] public var test2:Object;
then bound like this:
<fx:Binding source="test1" destination="test2" twoWay="true"/>
this obviously worked. I then tried something I imagined would be redundant, and copied the format of the cast I had tried to do earler between Object and Person (that had failed):
<fx:Binding source="test1" destination="Object(test2)" twoWay="true"/>
This failed with an 1105 error :Target of assignment must be a reference value. Swapping the cast over to the source side instead of the destination side produced the same error. Does this mean that the cast creates a new, immutable object that is unable to be referenced in a bind?
If so, what methodology/best practices should be used to go around this problem? If test2's class was changed to be "Person" rather than object, and I knew that test1 was an object that was originally created as a Person object, how can I ever bind the two?
Thanks in advance for any help! =)
