checkbox not showing as parameter?

I'm using an Ext.form.field.Checkbox on a form. Here's me creating it:

Code:

---

    var activeCheckbox = Ext.create('Ext.form.field.Checkbox', {
        id: 'detail-active',
        name: 'active',
        inputValue: 'x',
        uncheckedValue: 'y',
        fieldLabel: 'Active',
        labelAlign: 'top',
        submitValue: true
    })

---

But on submission to my Java servlet, I don't see an "active" parameter. If I use a normal HTML checkbox it works.

One thing, I have the checkbox embedded in a panel, with date & time selectors. The servlet picks those up as parameters.

Looking at the generated source, I don't see name="active" attached to the ExtJS generated checkbox element, but I do with the date & time selector.

Anyway, not sure if I'm missing something. Any help appreciated!

With this:

Code:

---

new Ext.form.Panel({
    renderTo : document.body,
    url      : 'data/form.php',
    items    : [
        {
            xtype          : 'checkbox',
            name          : 'active',
            inputValue    : 'x',
            uncheckedValue : 'y',
            fieldLabel    : 'Active',
            labelAlign    : 'top',
            submitValue    : true
        },
        {
            xtype  : 'button',
            text    : 'Submit',
            handler : function(btn) {
                var form = btn.up('form');

                form.submit();
            }
        }
    ]
});

When I submit with it checked it sends active : x and when it's unchecked it sends active : y as expected for me.
