jQuery Grid Plugin - jqGrid

The variable gdata on line 579 of grid.base.js is now undefined (all other references to it were deleted or changed to ts.p.postData). Should it be changed to ts.p.postData, or is there still a need to extend it with ts.p.searchdata, as in this line that's been eliminated?

if(ts.p.search) gdata =$.extend(gdata,ts.p.searchdata || {});
