Do your database rows reflect what you're seeing in your browser?
I.e., has each object been related many-to-many to all the destination
objects in the display group? If so, then the UI is probably correct
but something in your model or code is incorrect.
Have you set EOAdaptorDebugEnabled to true so you can watch the SQL
being generated? If so, is it correct?
In finding this code it has made me think that there is some vital
code I am missing when saving to a flattened many-to-many
relationship. Does anyone know if this is so and if so can you please
post it with a brief explanation on how to implement it if necessary.
If you used EOModeler to configure your many-to-many relationship and
you didn't modify what EOModeler produced, you shouldn't need any
special code. The flattened to-many relationship should behave like
any to-many relationship.
