["Hille-Doering, Reiner" <reiner.hille-doering@xxxxxxx>]

The links fit perfectly. I only remember that in one my plugins this registration happens either in code or in plugin.xml.  I assume that in Bob's modeler this registration is also somehow executed. But as I'm away from the project for such a long time, I don't exactly remember where and how this registration is done for the BPMN Ecore model.

Hi Bob, and Reiner,

thanks for your fast replies (wow!).

"Perhaps the packages are not registered?"

Considering that I have no idea what you're talking about, I suppose I
missed some part here.  What do I have to register? Where?  From Java code?

I found these 2 links [1] and [2] and I will try to work on this as the
moment but if you have better tutorial/documentation, don't hesitate!

Thank you.
