I get following error while merging a persisted entity A after adding new child entities to it.  The following relation exists between entities:  A -> (many to many) B -> (one to many) C.

The issue is I don't get this error while using openjpa 1.0.0, but I get it using openjpa 1.1.0. If I add "cascade= {CascadeType.MERGE, CascadeType.PERSIST}" to ChainEntityC.chainEntityB field It works with openjpa 1.1.0 but this time I have problems with openjpa 1.0.0.

I'm not sure if this is a bug or an older bug is fixed. Do we need to open a jira for this or not? My opinion is the cascade type on entity C should not be necessary because C is the last entity in the chain and should be cascaded from A to C. Cascade from C to B does not sound logical.

The test code is attached and works if you copy it to openjpa-persistence-jdbc test module.

Thanks.

Ekin Sokmen.
