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

Sunday, December 25, 2011

I’m not using 4.5.1 yet, so this observation is more “generic” than you may want. When using the tabnavigator without states, but just setting the index, I get this error if I try to access a variable/method in any child other than the first child. Apparently they are not created until they are displayed the first time. A possible solution is to display each one briefly in a loop at startup. Perhaps you could even make the container invisible so it’s faster – not sure.

Hope this helps,

Fred.

Subject: [flexcoders] Re: Problem migrating project from FB 4.5 to FB 4.5.1 - runtime error

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:
