Igor Sakovich updated OPENJPA-1141:
-----------------------------------
Attachment: openjpa-1141.zip
I'm encountered simular NullPointerException at
org.apache.openjpa.jdbc.meta.MappingInfo.mergeJoinColumn(MappingInfo.java:1415),
when trying to use Entities as part of Primary Key in 1.2.2. There is no such
problem in 2.0.0 and 2.0.1.
I've prepare minimal set of Entities that reproduces this error.
If I remove @JoinColumns from LineItem.order or remove Item.items — problem
goes away. If I rename Product to Customer (with corresponding changes in other
classes) — problem goes away too.

> We've reduced our complex intended target domain model (about 200+ Entities)
> to a simpler model with only 3 classes which illustrate the problem: You'll
> find attached a test project with a first entity which has a a OneToMany
> (with an ElementJoinColumns, but that shouldn't matter?) to a second entity
> has a ManyToOne to a third entity. The middle entity has a Composite ID Class
> including a ManyToOne as a key, which according to
> http://openjpa.apache.org/builds/1.2.0/apache-openjpa-1.2.0/docs/manual/ref_guide_pc_oid.html#ref_guide_pc_oid_entitypk
> is supported, so this seems a bug in OpenJPA's mapping algos, somehow?
