As far as i remember, the problem is if we have a mapping:
entities:
A
B extends A - mapped in same db table
C
dbRel:
toA, cArray (from C to A and vice versa) - Is Mandatory
objRel - toA, cArray (from C to A and vice versa)
So, there's isn't any ObjRel from B to C and therefore Cayenne adds
runtime
relationship.
Problems come when we're setting relationship via C.setToA(..) and
commit.
Cayenne thinks runtime rel from C to B is mandatory (after all, it's
mapped
to mandatory dbRel) and fails to commit.
Created a patch from this description against 3.0 branch:
https://issues.apache.org/jira/secure/attachment/12435122/CAY-1009-Andreys-case.patch
A == Sti2Inheritance
B == Sti2InheritanceSub
C == Sti2Related
I still can't reproduce the failure, as there's no runtime
relationship created between B and C, either with or without CAY-1009
commit.
