Hi,

I found that if I set frozen columns, then attempt a formedit (by clicking the pencil icon on the actions column), I'll get an undefined error at line 5275 (version 4.4.5) as $t.p will be undefined. I fixed it by changing line 5272 from this:

$grid = $(this).closest(“table.ui-jqgrid-btable”)

to:

$(“table.ui-jqgrid-btable”).first()

It looks like the closest selector was grabbing the frozen table instead of the initial one, and the frozen table didn't have the p attribute.
