Should Assignments be conditionals? Warnings in Flash Builder.

In these classes
robotlegs.bender.extensions.localEventMap.impl.EventMap and also robotlegs.bender.framework.impl.MessageDispatcher
…there are some assignments within conditionals.
Are these supposed to be like that ?

Error ( Did you mean == instead of =? )
Line 127 while (eventConfig = currentListeners.pop())

    Yes, they are meant to be like that. It's shorthand.
    With which compiler are you getting the warnings? ASC 2.0?

    I guess the old AS3 compiler understands that
    while (eventConfig = currentListeners.pop())
    is the equivalent of
    while ( ( eventConfig = currentListeners.pop() ) !=null )

    Are you using Flex and are you compiling against the rl source using the new ASC2?
    If the answer is yes, have you tried compiling using the SWC?

    See these issues on github:

    I use Flash Builder 4.7 using AIR SDK 4.0 ( I'm unsure what compiler that is, I'll look up how to find that out later when I have a moment ).

    This is not causing me a great problem, I am only getting warnings - I know that it's actually valid code, although I would say that for the sake of either a comment saying ( this is supposed to be like this ), or a little extra code to make it obvious what's going on and that it is intentional - I think it is worth doing.

    Thanks so much for your replies.

    Glad we could help:)
    I guess this is resolved? I'm going to close this discussion, but you can re-open it, if need be.
