This form sends the blank value:

new Ext.form.Panel({
    renderTo : document.body,
    title    : 'Test',
    url      : 'data/form.php',
    items    : [
        {
            xtype      : 'textfield',
            fieldLabel : 'Foo',
            name       : 'foo',
            value      : 'bar'
        },
        {
            xtype      : 'textfield',
            fieldLabel : 'Blank Value',
            name       : 'blank'
        },
        {
            xtype   : 'button',
            text    : 'Submit',
            handler : function (button) {
                var form = button.up('form');

                form.submit();
            }
        }
    ]
