Short answer:
Define properties (AKA Variables) in the subpod (AKA component). Use
parameter passing (potentially with data binding) to send variables from
the "main" component into the subcomponent.
If you're using a ViewStack, keep in mind that the view probably won't
be initialized until it is displayed, and accessing it will probably
cause errors.
Not sure if this helps. Your code sample is not enough for me to
diagnose the problem.
