My jqGrid (version 4.4.4) is not grouping based on field I specify, but is instead repeating fields.

Here is my json data derived from a php-mysql page:

{“rows”:[{“domain”:”example.com”,”email”:”admin@example.com”},{“domain”:”example1.com”,”email”:”dave@example1.com”},{“domain”:”example.com”,”email”:”dave@example.com”},{“domain”:”example2.com”,”email”:”admin@example2.com”},{“domain”:”example2.com”,”email”:”dave@example2.com”}]}
