Hi WOrriors,
A little late to the party but wanted to pass along that if you go to the
“entity” you can create an “identity qualifier” that works everywhere including
when you have a compound primary key.
For giggles, it would look something like so:
EOEntity entity = EOUtilities.entityForObject(eo.editingContext(), eo);
EOKeyGlobalID globalID = (EOKeyGlobalID)
eo.editingContext().globalIDForObject(eo);
NSDictionary primaryKey = entity.primaryKeyForGlobalID(globalID);
EOQualifier identityQualifier = entity.qualifierForPrimaryKey(primaryKey);
Cheers,
