After remove the class,  It works! 

Thank you, Thank you!!!

I am on 1.2.6 and using firefox; my datagrid seemly works OK for the most part, but I have notice thru FireBugs, that the data URL is being called 2 times, and on the 1st time, there is no query parameters sent.  My javasript is below, server is json service return all the alert records if the "serviceId" parameter is not specified, or return specific alert records when the "serviceId" is specified.

   $(function()
   {
      $('#tt-alert').datagrid({
         url: '<c:url value="/gui/alert/getFilteredAlerts.json"/>',
         width: 'auto',
         height: $(window).height()-200,
         queryParams: {serviceId: ${service.id} },
         onDblClickRow:function( rowIndex, row  )
         {
            genericEdit('tt-alert','alert-dlg','alert-form','Alert',true );
         }
      });
   });



In firebugs, I clearly see 2 calls URL, the 1st with the seviceId parameter and the 2nd without.  So, I like to understand (and fix)
1) Why the URL is being called 2 times.
2) Why the 2st call is without parameters
3) Why does the content of the datagrid seem random (sometimes result from the 1st call, and sometimes results from the 2nd call)


Any advise would be appreciated.
