In my application, I was bugging my head for a long time as my Tab Navigator was not getting initialized. Data was getting displayed on the first tab but for the other tabs, it was giving a null object reference error.Interesting part here is that if i navigate through all the tabs of tab navigator and then populate it , error was gone.
Reason being very simple, by default only the first tab is initialized and the others are not created.
By setting the property creationPolicy = all, this issue can be resolved.
I thought writing this point here as it took a lot of my time to figure this simple mistake.

Hi Rahul,
Welcome to the world of blogging :)
Nice job! I was stressing over the same issue. Thanks for posting!
Thanx, exactly what I needed. In Flex 2.01, however, you set to creationPolicy to "all". You also have to set it for any children on the tab/viewstack (i.e. embedded panel, etc.).
Thanks...I've been using Flex for 2 weeks now..and the TAB issues just poped up yesterday...I thought I was going to have to instantiant each object on tab before I could reference them...THANK YOU
thanks a lot man...
Hi Raul,
Great Job! Thanks for the hint!
craetionPolicy = "all"; for the Flex 3 ;)
Great! just about to start a painful debugging session to solve this problem, helped a lot (Flex 3)
Bless You....
That was driving me crazy.
I didn't see anywhere in the
Flex3 doc's where it say's only
the first tab is initialized.
Thanks a lot!
You saved me probably hours. How should one know that.

for days that has been annoying me. top man.
Thank you so much. This saves me some major headaches.
Hurrah!! Thanks.
A small thing but It's been bothering me for days.
Thanks for posting
How sweet it is. It does this in certain situations in Flex 3 as well. I thought I was going to have to recode the universe. Yikes! Thank you.
Thanx :)
Thanks! I've been trying to figure this out for a a couple days now. Thanks again! =)
Same problem here. Thanks for help

Wished I would have thought about searching for issues with the tabnavigator sooner.... after wasting several hours and even trying to rebuild my app from scratch, came across your post - definitely thankful!
Thanks dude, I was searching for this :d

Thanks. I stumbled upon this issue being posted by others once in a while (when researching for different problems than that, hehe), so when i got into that issue right now, i remembered that subcomponents of tabs other than the first aren't created yet.
So, luckily i found a quick solution. Thanks. :)
Thanks, exactly what I needed. You saved my time. once again thanks...
