You didn't write anything about jqModal, jqGrid, jQuery UI and jqQuery version you use. There is some problem if you try to use jQuery 1.4. I posted /blog/?page_id=393/bugs/jqgrid-jquery-1-4/ described the problem and the solution. The problem is that jqModal.js use “$()” instead of “$(document)” which works in jQuery 1.3, but not works in jQuery 1.4, so the code of jqModal.js must be fixed. In the last version of jqGrid the problem is fixed, but the last r14 official version from http://dev.iceburg.net/jquery/jqModal/. So first of all verify that in you version of jqModal.js all “$()” replaced to “$(document)” and if you have nevertheless the problem, describe exactly your environment and post a small code example, which reproduced the problem.
