I am having a problem where the parent window is controlling a popup child window, and when the parent window refreshes or changes a query, the child window var gets nulled, forcing the child to refresh.
What is a way to solve this by still controlling a child after parent refresh without using frames.
I have read about PDOM Persistant Object Document Model. But I just don't understand how to use it in this scenario. Advice with an example would be much appreciated!
