Hi All,

Just a quick followup question for my additional knowledge.

There is a method in EOCustomObject.__globalID(). Any reason why using this should be avoided?

Thanks,
Amiel

While trying to return an EOGlobalID for a generic record, I am getting a null.

I have a method to fetch a student:
private static EOGenericRecord getStudent(EOEditingContext ctx, String sid) {

EOGenericRecord student = (EOGenericRecord) EOUtilities.objectMatchingKeyAndValue(ctx, "Student", "studentId", sid);

ctx.insertObject(student); //tried with and without inserting it into the context

insertObject() is only for newly created objects, not fetched objects. Fetching places the object into the EOEditingContext.

return student;

}

Later I try to retrieve that object's EOGlobalID with the following:
EOGlobalID globalID = ctx.globalIDForObject((EOGenericRecord) value);

The value of globalID is always null. What am I missing?

that only works if ctx is the same object instance in both cases. Try the seemingly redundant:

EOGenericRecord eo = (EOGenericRecord) value;

EOGlobalID globalID = eo.editingContext().globalIDForObject(eo);

If you get an NPE, then eo is not in an editing context.

Thank you for any help you may be able to offer,
