jQuery Grid Plugin - jqGrid

I have detected two bug recently.

1) When i tried to use two grid in one page with toolbox search, while trying to use search, one of them not working properly and throwing a js exception,  but other is working good.

2) When i tried to delete a record, grid sends me a id data that is i specified as key before. But my key is date type and returned id is not formatted. (i solved that with a psedeu key cloumn that's type is string, hidden and includes same data with date cloumn)

- My other views are working properly with same intalliation so no installation error.

- In form edit in all views, dates are working properly so no javascript description error. You can easly simulate this bugs yourself.

- I think, optionally sending all data to client on delete like update and add may be good.

Thanks for this great grid.
