It should still work.
You would have an action on the AjaxObserveField that points to a method on the
Java class. The AOF would wrap popUp1. The AUC wraps popUp2.
When the popUp1 changes, the action will trigger and call the server method.
In the server method you would use the objectSelection to fetch the data for
the popUp2. Then when the AjaxUpdateContainer of popUp2 refreshes, the data
fetched previously will be there.
I believe that's how it works.
