First, i'd like to say that this is a great project – congratulations!

My English is not very good, but I'll try.
So, I'm working on a firewall solution and would like to share the experience with jqgrid. I get the data remotely in json format, but i manage the information only in memory (client side). For this reason I needed to use the “loadonce” and use clientArray in editUrl. And I save everything (with ajax) in the end (save button).

The difficulty was that i get the data sorted by the server. But, to update “grouping” a need a “reloadGrid” after insert, edit, clone or delete operations.
