jqGrid error at line $t.p.colModel[lvc].width += cr;

Recently I am getting an error in jqGrid plugin at the following line :-

$t.p.colModel[lvc].width += cr;

After debugging through the code this issue occurs with in the function

setGridWidth: function (nwidth, shrink)
.....
$t.p.colModel[lvc].width += cr;
.....

where nwidth is null

So while calling method setGridWidth on a grid make sure the width is a definite value and is greater than 0

Control is the wrong word. The practice is very much about sharing, and, in any creative practice, some individuals, whether partners or directors, are much closer to certain projects than I could ever be.
