Hello-
I am having a strange problem with our application on WebObjects 5.4
(not sure if it was present on 5.3, just giving some background).
The error occurs when I attempt to delete an object which has a
flattened relationship. The error I get is:
java.lang.IllegalStateException: A valid global ID could not be
obtained for entity named UnknownStatusPolicyReportItem,
relationship named policies, primary key dictionary {policyID = 169;
reportID = 15; }.

deleteReport
The model classes involved are Policy, UnknownStatusPolicyReport,
and UnknownStatusPolicyReportItem. UnknownStatusPolicyReport is a
subclass (using single-table inheritance) of Report. A
UnknownStatusPolicyReport has a to-many relationship to
UnknownStatusPolicyReportItem, and UnknownStatusPolicyReportItem has
a to-one relationship to Policy (each item in the report points to
an insurance policy). I defined a flattened to-many relationship on
UnknownStatusPolicyReport called policies which is defined as
"items.policy". I also set the delete rule on the
UnknownStatusPolicyReport items relationship to Cascade so the
UnknownStatusPolicyReportItems get deleted when the
UnknownStatusPolicyReport is deleted. The code that does the delete:
public WOComponent deleteReport() {
Session s = (Session) session();
s.user().removeFromReports((Report)entity);
Is s.user().editingContext() == entity.editingContext()?
session().defaultEditingContext().deleteObject((EOEnterpriseObject)
entity);
session().defaultEditingContext().saveChanges();
return null;
}
Any assistance would be greatly appreciatedI am sure I'm missing
something fundamental here about how EOF works.
Thanks,
Greg
