IllegalArgumentException with master-detail UI

Hi Kirill,
thanks for your answer, I now know how to handle this via the instance.

But coming back to my real application with the Oracle DB another problem raised that I really don not understand.
I defines 3 tables, one in the middle (PRO) and two related tables (HST and PRT), both defined in the same way.

I then wanted to define a new view on entity PRO with the relations to the others, see below:
grafik

running the application WITHOUT having defined a UI I get the unexpected error:

grafik

just removing the HST relation in the view (see below) then the application runs without error:

This is very curious and I donā€™t have any idea how to solve the problemā€¦

good morning, I think I solved the problem, gradle was still runningā€¦
