That's an interesting approach. One can invoke an action in the a4j:support tag and via immediate="true" it gets executed during APPLY_REQUEST_VALUES - so this would be possible. But yes, it is weird and I refrain from using this *brrr* ;). I even tried out a4j:region and multiple other tags, but they couldn't help me. But I must confess that I just try out blindly and that I didn't get smarter by reading the documentation (parts of it are really not easy to understand for a non-native speaker like me ;)).
