(How to create a form with a custom graphics representation in RTC): AFAIK, but I'm no expert, you only have one field for the AddIn as a direct data channel to the page. For what EHernandez wants, this is quite a bottleneck, IMO. He has several controls ("Table", "Table State" at least, by table) to manage. Going through only one field might be doable, but it is a pain. Or am I missing something?
with best regards
