javascript - free-jqgrid: clearGridData problems -


i having strange problem using free-jqgrid 4.9.0. when load data grid using 

$('#list').jqgrid('setgridparam', {data: filtereddata}).trigger('reloadgrid');

everything works fine; data added current grid. duplicates way, wanted delete data before adding it:

$('#list').jqgrid('cleargriddata', true); $('#list').jqgrid('setgridparam', {data: filtereddata}).trigger('reloadgrid');

this clears content of jqgrid fails add new data.
long don't use clearing-part, adding works perfectly. when want add data cleared grid, doesn't work @ all.

thanks or suggestions!
