I'm running into some errors when trying to hang supplementary associations off of a join entity.
Ie StudioCompetition is a join entity that replaces a direct M:M between Affiliation and Competition that provides a place to hang additional qualifies of the association.
I can't seem to figure out how to allow hook up the extra associations -- I get errors regarding the number of columns in the foreign key.
My current setup looks like:
which yields an error like:
Earlier I had the association on the StudioSessionPrice named "affiliation" of Type Affiliation... so it wasn't really bi-directional (more of a loop). Which fails with a similar error message -- different wording, but same general intent -- wrong number of columns.. That error made sense since I had the mapped by of something with a two column PK mapped by a single column/wrong type. So I switched to the code shown above.
Is there a way to back the supplementary association work? Or do I need to lose the compound primary key, add an artificial key to the join table and just treat it like a regular entity? [ December 25, 2008: Message edited by: Eric Nielsen ]
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
