selectCell in jsp example


in the jsp example, when adding a new row to grid the function addNewRow

call the method mygrid.selectCell(mygrid.getRowIndex(newId),1,true,false,true)//put cursor into 2nd cell in new row

to turn the 2nd cell editable automatically

but in both my browsers (firefox, ie) all that heappens is that the row appears as selected, and the cell editor dont open

what could be wrong?
