I have fixed this bug. Currently it is available only in jqGrid 3.5 Alfa 2. I will publish a stable 3.4.4 version soon.

The workaround that i am using now is to cause all subgrids to collapse when a sort command is called on the parent table.  So, i implemented the onSortColumn() method along with adding code to the subGridRowExpanded and subGridRowCollapsed() functions to save the list of currently open subgrids as follows (this is for other users, if they would like a workaround):

var openSubGrids = new Object();
...

    onSortCol: function (index, colIndex, sortorder)
    {
        // go through all subgrids and collapse them
        for (var name in openSubGrids)
        {
            jQuery(”#list2″).collapseSubGridRow(openSubGrids[name]);
            delete openSubGrids[name];
        }
        //alert(index + ” ” + colIndex + ” sortorder: ” + sortorder);
    },
    subGridRowExpanded: function(subgrid_id, row_id)
    {
        // store the subgrid_id and row_id somewhere
        openSubGrids[subgrid_id] = row_id;

    },
    subGridRowColapsed: function(subgrid_id, row_id)
    {

        delete openSubGrids[subgrid_id];
    }

Thanks!

Thanks for this. It is true. Will think how to avoid this.

Thanks again

I am having trouble with local sorting of a parent grid when a subgrid is currently open.  Both the parent grid and the subgirds are of the datatype, 'jsonstring'.  Therefore, when you call sortGrid or click the header of the grids, it wil do local sorting as opposed to server-side sorting.

When the above scenario occurs, i.e. attempting to sort the parent grid while a subgrid is open, it will cause an inifinit loop on the subgrid, and you will see multiple subgrids of subgrids until the browser (in my case, Firefox) crashes and no longer responds.

I took the subgrid as grid example and modified it to use json strings so that it can to local sorting.  The following is my configuration:

var jsonstring = '{ total: "1", page: "1", records: "10", rows: [ {r_serviceName:"MediaService2_0", r_deploymentName:"pubwsv2_axis2", amount:"124", tax:"123", total:"1234", note:"somenote" }, {r_serviceName:"LookupService", r_deploymentName:"pubwsv2_lookup", amount:"124", tax:"123", total:"1234", note:"somenote" }, {r_serviceName:"IdentityPointService", r_deploymentName:"bamwsv2_axis2", amount:"236", tax:"95", total:"654", note:"somenote" }  ] }';
var subjsonstring = '{ total: "1", page: "1", records: "10", rows: [ {sub_r_serviceName:"MediaService2_0", sub_r_deploymentName:"pubwsv2_axis2", sub_amount:"124", sub_tax:"123", sub_total:"1234", sub_note:"somenote" }, {sub_r_serviceName:"LookupService", sub_r_deploymentName:"pubwsv2_lookup", sub_amount:"124", sub_tax:"123", sub_total:"1234", sub_note:"somenote" }, {sub_r_serviceName:"IdentityPointService", sub_r_deploymentName:"bamwsv2_axis2", sub_amount:"236", sub_tax:"95", sub_total:"654", sub_note:"somenote" }  ] }';

jQuery("#list2").jqGrid({
