I have a problem with the RibbonTab and Prism.
I can add one RibbonTab to the Ribbon wich has a Regionmanager-Region inside. Thats fine.
But if I add a second RibbonTab (another Module), the Action of the Add is set to RESET and the second RibbonTab is not show in the Ribbon.
If I do this code at the first time, is all fine:
But a second Tab will not add. As I wrote, the action (Behavior) of the Ribbon ist Reset.
How can I solve this problem?
