Whenever I bump into this, and annoyingly, it still does happen once in a while, the thing to fix is either: - one of the 4 underlying relationships are marked as a class property, or - one of the underlying relationships into the join table does not have 'owns destination' and 'propagate primary key' set. Either of these can cause it. I do not let eclipse create many-to-many relationships for me anymore. I just do it myself. Maybe I have had enough practice and screwed it up enough times that I now know what to avoid. - ray > Le 5 avr. 2013 à 17:43, Markus Ruggiero <mailingli...@kataputt.com> a écrit : > >> As others already pointed out your many-2-many looks strange. >> >> Delete your all relationships from and to your join entity >> EORepartDomMatiere.
