jqGrid - оставить флажок при перезагрузке сетки при редактировании формы

Question

У меня есть форма, которая использует jqGrid для отображения персонализированной информации для выбора пользователем. Все работает нормально, однако на странице «Обзор» есть возможность редактировать форму. Когда вы нажимаете «Изменить» и возвращаетесь к выбору формы, все выбранные значения сохраняются, за исключением части формы jqGrid, в которой используются значения флажков. Как сохранить это значение, чтобы пользователю больше не приходилось делать выбор?

var myGrid;
var blnListsFound = true;
var blnGridLoading = false;

function fnInitialize() {
    // Initialize the screen
    fnLoadForm();

    $('#no_transactions').hide();

    // alert("fnInitialize(): JS loaded fine, no errors");
}

function fnACHSwapGetGrid() {
    blnListsFound = true;
    // make sure we have a from account

    if ($('#selFromAccount').val() == '0') {
        return;
    }


    $('#imgWaitselFromAccount').show(); // show loading icon

    var urlString = '';
    var urlParams = new Array();
    // urlParams['rc'] = escape($('#RC').val());
    urlParams['RC'] = escape($('#txtMenuRC').val());
    urlParams['acctNBR'] = escape($('#selFromAccount').val());

    // get application type from aryAccount
    for (act in aryAccount)     {
        if (aryAccount[act]['Number'] == urlParams['acctNBR']) {
            urlParams['Appl'] = aryAccount[act]['Application'];
            break;
        }
    }

    $.jgrid.gridUnload("#list");

    myGrid = $("#list").jqGrid({
