I've been using jqGrid 3.7.2 for over a year & its working fine. I now have a numeric column in which I don;t want zero values to show up and I want sortable. I created a custom formatter to strip out zeroes and an unformatter to put them back in for sorting algorithm purposes. I've tried using not a “” as a zero replacement and ” ” but I can't seem to get the unformatter to work and the sort breaks. Any help/suggestions are appreciated. I'd prefer NOT to upgrade the grid version at this time, but if that's a definitive answer I'd consider it. Informal testing suggests the problem exists w/v3.8.2 and 4.1.0.

Formatter & unformatter:

function noZeroNumberFormatter(el, cellvalue, rowObject) {
