Hi i having problem with deleting of an entity. The entitymanager would not remove the entity. Do anyone see the error in the code?
Error message:

Answer 1

I just figure it out. It was an error with my testfile =)
I needed to change the method to get a instance, and delete with the method rather than through entityManager =)
Case solved
