Is there a way to mark container, node, or layer as not movable in Sirius after its initial layout.
This would be to help me with an issue I raised at https://www.eclipse.org/forums/index.php/t/1097301/ where moving a container gives me layout problems.

Thanks,
Neil

Hello,

I am not a fan of not movable elements as containers can grow because of their nodes and overlap some other diagram elements and you would be stuck with it. Anyway, I think you can try by adding a new ModelChangeTrigger to the SessionEventBroker (accessible with org.eclipse.sirius.business.api.session.Session.getEventBroker()). In this ModelChangeTrigger, you will need to return an UnexecutableCommand if the notification concerns an X or Y coordinate update.

Regards,
Steve

Thanks Steve,
I might give this a try. I agree it is not the best approach in general, but it might suit my particular use case well.
