I try to use the FluentRibbon with Composite WPF (Prism).
The concept being that modules provide RibbonGroupBoxes, RibbonTabItems or ContextualTabs.
And it happens that the tabs are without content - I think that is related to the themes dictionary.
When I first only had it in the App.xaml the tabs showed up but without content.
I also added it to the resources of the RibbonWindow, than the tab had content.
I added a RibbonGroupBox from another module - that worked.
Now I tryied to add a tab from another module - again it is without content. I added the themes dictionary there - but still no content.
I don't really understand why... and what can i do about it?
