jQuery Grid Plugin - jqGrid

When rowid is empty string, jqgrid does not allow edit or view row, due to wrong checks for rowid.

However with the following fix (check for rowid==null instead of !rowid), it works, and send correct data to server.

Warning message "Please, select row"  still appears, I havent found where to fix that.
