I really need to have a boilerplate answer for this one! The issue you describe is caused by the fact that Accordion and the other navigator containers by default use a feature called "deferred instantiation", where a child view is not rendered/instantiated until a user first navigates to that view.
Deferred instantiation helps to speed up the initial load of an application, improving the user's experience. The correct way to handle this issue is to use data binding or your own event system to "pull" data into the view when it is rendered, instead of trying to access members in the child view from "outside". A quick an dirty fix, to determine if this is your p[roblem, is to set creationPoliccy="all" on the Accordion. But remember, this can hurt the percieved performance of your app when the child vies become complex.
