All Over Software Jobs: [flexcoders] Re: Problem migrating project from FB 4.5 to FB 4.5.1

Sunday, December 25, 2011

have you any solutions from this yet?

I am having the same problem when i am making changes in views.
In my case, I wasn't using visual states to make state transitions however through dynamically adding and removing elements.

null reference error with the following msg:
