Javascript Window Class: Ajax update parent window

[ricslabb03]

My parent form uses Fabrik's javascript window class to open a popup window to another fabrik list.

I know that this is a shot in the dark question, but I was wondering if it is possible to update fields dynamically in the parent window based on new values saved in the child window?

Another alternative is to save and refresh the parent window after closing the child, but I am unsure of that as well.

Any help or ideas would be appreciated.
