Adrian - thanks for the clarification of which JBoss versions this problem has been
fixed in. We have managed to code a work around for this as indicated below.
Essentially, we are explicitly deleting the related child entities by cycling thru the
related collection and applying the remove method. i.e We are manually performing
the cascade delete at this stage. When we do eventually upgrade to a version >=3.0.4
we shall re-examine this area and see how we go.
Thanks again for your support
Regards
Alan.
public void removeJob(String erpId) throws RemoveException, FinderException,
ObjectNotFoundException
{
JobLocal job = jobHome.findByErpId(erpId);
// TKH 25/10/02 added code to remove assignments before removing job as a work
around for the
// IllegalStateException which is thrown if JBoss has been restarted since the
job was created.
AssignmentLocal assignment;
Collection assignments = job.getAssignments();
Object[] assignmentsArray = assignments.toArray();
for (int i = 0; i < assignmentsArray.length; i++)
{
((AssignmentLocal) assignmentsArray[i]).remove();
}
job.remove();
}

revisited
Hello Alan,
The fix(es) are in 3.0.4 which has not yet been officially release.
But you can get it from CVS.
Try setting your cache size to something very small like 1. :-)
You should be able to reproduce the most likely cause of your
problem.
If 3.0.4 does not fix your problem, please feel free to open a bug report.
Regards,
Adrian
