Any idea?

Hi ! Yes, I have a little idea, using it for all my projects :D

Infact, it is due to an inconsistency in your entities mapping : You probably forgot the mappedBy or the inversedBy in a bidirectional relation between two entities.

To fix this, you have all what you need in the profiler toolbar : the error should put a link in red ;)

I could make a more explicit message in this exception, indicating the classes involved... I'll think about it.

Hope that helps ^-^

Hi! Yes, you are right! I forgot a bidirectional relation annotation.

Thanks!!

pleasure :)
