Use of @EmbeddedId (composite) and relation fields results in exception

Created: 11/Feb/10 12:24 PM   Updated: 06/Feb/12 10:13 AM   Resolved: 19/Jan/12 03:49 PM
Component/s: Persistence
Affects Version/s: 2.0.0.release, 2.0.1
Fix Version/s: 3.0.6


 Description  « Hide
See test.jpa.general RelationshipsTest where there is a test with @EmbeddedId and with the owning class also having a join table 1-N relation. When the persist is attempted it tries to insert into the join table with null for the owner PK fields. The problem is likely the internally selected objectId class (ObjectIdentity) which doesn't allow for fields that are persistable in their own right. The workaround would be for the user to define their own @IdClass.

Likely due to the @EmbeddedId class being set with nondurable identity and AppIdObjectIdConsumer doesn't handle that case (needs to use all fields of the class, instead of the PK fields)

SVN trunk has a fix that results in the test passing
