Please use this patch to get rid of the error. Add it after including pqgrid js file and before initialization of any pqgrid.
$.paramquery.pqGrid.prototype.getCell=function(e){if(e){e.vci>=0&&(e.colIndx=this.iCols.getci(e.vci));var i=this.normalize(e),r=i.rowIndxPage,t=i.colIndx,l=this.iRenderB.getCell(r,t)}return $(l)};
