[SOLVED]Rép : Re: Relationship many-to-many issue
Hi List,I deleted many-2-many relationship created by reverse engineering, deleted joined table and recreate relationship and joined table has been created automatically and it works fine.My question is why the relationship one-2-many create by everse engineering works fine and the relationship many-2-many don't work?Thanks a lot for allEnvoyé depuis iCloudLe 05 avr 2013 à 20:31, Ray Kiddy r...@ganymede.org a écrit :On Apr 5, 2013, at 9:04 AM, Raymond NANEON wrote:Hi Markus,Thanks for your advices. i going to try itRayEnvoyé de mon iPadWhenever 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.

Likely your database design is different from what EOF normally uses and it got confused when reverse engineering. Or the reverse engineering code has a bug. That code does not get used every day, so bugs are a possibility.
