Hello again Pinaki et al,

We ran into this again recently, and after some debugging and reducing a
more complex model to a simple version that reproduces this, I've
finally understood what causes this
org.apache.openjpa.persistence.PersistenceException: ...
org.apache.openjpa.kernel.StateManagerImpl.setExtraFieldData(StateManage
rImpl.java:720), under v1.2.0.
It's turns out to be actually pretty simple, to reproduce at least:
Create a simple domain model with an class A { @Id String code;
@PersistentCollection(elementEmbedded = true) Set<B> bs; } and class B {
@ManyToOne C cReq; } and class C { @Id String code; }. Create an A/B/C
and query the A by it's ID/PK code. The a.getBs() --> BOUM! I could
send the real .java for this simple test model by direct email, if of
any use.
Question: Is it simple to fix also? ;-) If that's "not supported", then
please say so in Doc and clear Error Message... :-) but I suspect this
may not be intended. Why? Because that
https://issues.apache.org/jira/browse/OPENJPA-593 is also about
@PersistentCollection(elementEmbedded = true), but agreed that's not the
same as this, however note what it's error message says: "Embedded
element/key/value types are limited to simple fields and direct
relations to other persistent types." ... and a "direct relations to
another persistent type" is exactly what that @ManyToOne C cReq on B is,
isn't it?
Should I file a JIRA?
Regards,
Michael
