jQuery Grid Plugin - jqGrid

Hi to all and thank you for this great piece of code.

I'm trying to make a search page with the possibility to save parameters to recall the search later.

I use the following code to show the problem:

    var grid_conf=jQuery("#find").jqGrid('jqGridExport',{exptype:"jsonstring"});

    jQuery("#find").jqGrid('GridUnload');
    
    jQuery("#find").jqGrid('jqGridImport',{
        imptype: 'jsonstring',
        impstring: grid_conf
    }).trigger("reloadGrid");
}

When there are filter data (toolbar with stringResult:true or dialog search) the import fail with this error (from firefox console):

Otherwise everything work as expected.

Notice that jsonstring data are exported and imported without any intervent.
Maybe a bug???

I use jqGrid 4.4.0 and jQuery 1.7.2 and jQuery UI 1.8.21.
For every test i'm here and thanky to all for all.
