I am trying to make architecture for my project. And for it, it needs to make list property in which there is list of objects of another table, the data must be unique, therefore I make sql-query to check objects of another table if it is used or not, but I can't make sql-query to check elements in list in property with elements of another table. Can you help me? In property ID of object is used.

Atelier: Install

I've installed Atelier according to instructions but after rebooting Eclipse there is not opportunity to launch Atelier. In preferences there is not Atelier. I've tried to update and reinstall Atelier but it didn't get a result. I checked it was installed on my PC.

How can I solve this problem? And why I faced to this situation?

All needed components were been installed earlier.
