I have a Tab Navigator with two tabs. On the first tab I have
a check box that when clicked should set some checkboxes on the
second tab. When I do this I get the following error message:
TypeError: Error #1009: Cannot access a property or method of a
null object reference.
I noticed if I click the second tab then go back to the first
tab and click the check box it works fine. Is there a way to access
the items on the second tab before the user views it?
