I'm trying out the uml-designer plugin and a tutorial ask me to select 'UML Structural Modeling' -> 'Class diagram' in the 'Create Representation Wizard'. But when I open the wizard it's empty. Is this a known issue or am I missing something?
I had exactly the same problem. The solution I found: Right click on your project in the "model explorer" and click on "Migrate to UML Designer 4.0" . Than, everything worked as expected.
