All:
I have some fetches that are not respecting the restricting
qualifiers in my model for a simple inheritance structure. I'm
using WO 5.4.3. This what I have:
Job >> Approver > Employee
I have subclassed Approver into PrimaryApprover and DelegateApprover
with the following restricting qualifiers. I am using single table
inheritance and applying a qualifier on the attribute 'foo.'
PrimaryApprover - foo=1
DelegateApprover - foo>1
So, there also is:
Job.primaryapprovers()
Job.delegateapprovers()
Here's where I'm seeing trouble. I have a qualifier set to fetch Job
entities and it is defined like so:
EOKeyValueQualifier
("primaryapprovers.employee",EOQualifier.QualifierOperatorEqual,
someEmployee)
Whenever I perform a fetch against the Job entity with the above
qualifier it appears to fetch against the Approver without any
restricting qualifier (foo>1) being part of the fetch. When I log
out the sql there is no mention in it of the foo attribute. I can
group two qualifiers and use an EOAndQualifier and that works, like
so:
EOKeyValueQualifier
("approvers.employee",EOQualifier.QualifierOperatorEqual,
someEmployee)
EOKeyValueQualifier
("approvers.foo",EOQualifier.QualifierOperatorEqual, new Integer(1))
But then I'm not leveraging the incredible work I've done to use
inheritance. :-) Does anyone have any idears why I am seeing this
problem?
Thanks for the help,

Is Approver marked as Abstract in the model? How is the
primaryapprovers relationship modeled?
