I don't think that is what's happening, when i use "if (i is B)" the condition does work, it enters the if block but it resets the C object.
I tried a new thing, on B i changed the myC declaration public var myC:Object; // Object instead of C By doing this i can use if (i is B) and now it doesn't reset the values of myC, but the problem is that if i try the following: if (i.myC is C) this gives me false :( Any ideas? --- In [email protected], "Josh McDonald" <[EMAIL PROTECTED]> wrote: > > Sounds to me like you're accidentally declaring b.myC as a static, perhaps. > > Actually, double check your examples (perhaps using the link report option > on MXMLC).
