Although redundant, that does work! Thanks to you and David for the solution.

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.
