Ext.NET forum thread: setFieldLabel on a CheckBox hides it

Whenever a form field's updateIndicator() is called, if no indicator has been set up to the field, the whole checkbox is hidden regardless of its display status. It always hides with the display:none CSS inline rule applied to the indicatorEl.parent() DOM element, which in this situation happens to be the whole checkbox.

Because the checkbox needs special fieldnote handling, it also needed special handling to hide and show the validity indicator, which occured in the related issues #1417, #1567, and #1569.

In the context of this issue report, the checkbox is hid when is called. This error is issued in core/form/FieldExtensions.js, where it calls this.indicatorEl.parent().setStyle("display", "none");.

This is not a Sencha related issue, as shown by this fiddle:

    name: 'Fiddle',

    launch: function () {
        var btn1 = Ext.create('Ext.form.field.Checkbox', {
            text: 'Click me',
            handler: function () {

                alert('You clicked the button!');

            xtype: 'panel',
            renderTo: Ext.getBody(),
            items: [{xtype: 'checkbox', fieldLabel: 'checkbox'}, {
              xtype: 'button',
              text: 'change label',
              handler: function(){
                  this.up().down('checkbox').setFieldLabel('new cbox');

The fix makes it smarter when hiding the indicator, so that it does not hide the parent DOM element whenever it is not the expected '-indicator' wrapping div.
