Summary: Read-ahead fails on one-to-one relationship
Initial Comment:
OS: Linux Redhat 9/Windows XP
JDK: 1.4.2
JBOSS version: cvs head as of 1/21/03 (3.2.4 R1)
Since JBOSS only allows one table per bean, we simulate
inheritance of entity beans using delegation. So say
Bean A is a base class, Bean B has a getBeanA() method
which delegates all "inherited" calls through this
one-to-one relationship. This has worked correctly on
past releases of JBOSS. However in the version I built
off the cvs head, we noticed the following behavior by
stepping through the cmp code. If Bean B has a preload
strategy of none, than everything works correctly. I
can read one or many Bean Bs and everything works.
However, changing preload strategy to either
on-find/on-load, causes the following exception only if
multiple bean Bs are returned by a finder (the first
one successfully is read and cached, the error occurs
on the second bean always retrieving the getBeanA
relation from the preload cache)

We are just if something has changed to cause this to
no longer work. Preloading strategy seems to work
correctly for other one-to-one relationships, just not
this particular relationship
Thanks,

Let me start with providing you the trace you need and the
source for the two beans involved. I believe the declaring
right, but maybe you will spot something looking at the
xdoclet. SecurityBean is the "inherited class" and EquityBean
is the "derived bean". The relationship that is failing is the
getSecurity() relationship.

I've attached a zip file containing the two beans. Let me
know what else you need.

The foreign key must be mapped to primary key column[s]. I
need more details to reproduce this. My simple tests pass.
This stacktrace snippet does not help. It would be helpful
to see the stacktrace starting from JDBCCMP2xFieldBridge. If
you have a testcase, please, attach.
Thanks.

Just to clarify, this works correctly with JBOSS version
3.2.2RC4 and 3.2.3RC1, but not in 3.2.4RC1 that we built
from the cvs head.
Thanks again,
Rich
