Re: [Flashcoders] fileReference failing silently

[Juan Pablo Califano]

The issue here is quite likely the garbage collector doing its job...

You FileRefence object is referenced only in a local variable in
the deskClickHandler method. After the method returns, since there's no
other reference to it, it's eligible for collection. So it might stick
around or not. In your case, it seems it doesn't. Try storing the fileref in
an instance variable instead. It should fix it, I think.
