  • DynamicForm.submitForm() sends null value for fields which are hidden


    I am using smartClient v10.0 for my project. I have a dynamic form which has two fields of type hidden. When we submit the form and send the values of the fields to a servlet, it sends null. When I make the type of the fields as 'text'. it sends correct value. But as per the requirement we want the fields to be hidden. I will appreciate if you can help me to resolve it.
    I have attached the code snippet below:

    DynamicForm used:
    exportForm: isc.DynamicForm.create({
    action: "mypipeline/export.xls",
    canSubmit: true,
    target: "_blank",
    height: 1,
    fields: [
    {name: "titles", type: "hidden"},
    {name: "data", type: "hidden"}


    Method used to submit the form:
    processExport: function() {
    try {
    var fields = this.grid.getFields();
    var titles = [];
    for (var j = 0; j < fields.length; j++){
    titles[j] = fields[j].title;
    var rows = [];
    var data = this.grid.getData();
    var i = 0;
    var sourceRec = data.get(i);
    while (sourceRec != null) {
    var rec = [];
    for (j = 0; j < fields.length; j++) {
    var value = sourceRec[fields[j].name];
    if (value != null && value.toSerializeableDate)
    rec[j] = value.toSerializeableDate().substring(0, 10);
    rec[j] = value;
    rows[i] = rec;
    sourceRec = data.get(i);
    console.log("Posting " + rows.length + " rows (" + titles.length + " fields)");
    titles: isc.JSON.encode(titles),
    data: isc.JSON.encode(rows)
    catch (e) {
    isc.warn("Error exporting data.", e);

    Thanks in anticipation!

    Is it a bug or is there any way to send data to URL directly from a Dynamic form which have hidden fields?

      Please try this with the latest patched build (see and be sure to always do so in the future, as well as posting your full version (not just 10.0).

        SmartClient Version: v10.0p_2015-09-03/LGPL Deployment (built 2015-09-03) is the version and built I'm using for the project. I cannot change the version as per the requirement of the project. But, I tried the patch SmartClient_v101p_2017-05-09_LGPL but still same error persists.

          Is there any way if I can make a form not visible yet able to post the details directly in an URL?
