You're probably trying to access children of a tab that has not been initialized yet. The simplest solution is to change the creationPolicy property of your TabNavigator to "all".

You can see an explanation of creationPolicy in the Adobe documentation.

If this is not the solution, you're probably going to have to post more specific code.
