    Default 1.1.0: Bug with "return false" from Ext.form.ToggleField#beforechange listener

    Sencha Touch version tested:
    • 1.1.0
    • only default ext-all.css

    Platform tested against:
    • Latest desktop Chrome (should be platform-independent)

    • Returning

    Test Case:

    See this URL :
    There's a JS error that happens on page render, but this doesn't appear to have anything to do with the bug at hand (and this page gives similar results to my app, which does not have any JS errors).

    Steps to reproduce the problem:
    • Run the above fiddle.
    • Try to check the field.

    The result that was expected:
    • The toggle field doesn't change at all.

    The result that occurs instead:
    • The class for the toggle field changes (although the value doesn't), making the toggle turn green when it shouldn't.

    Possible fix (change in bold):
    Ext.override(Ext.form.Toggle, {
       setValue: function(value) {
  , value, this.animationDuration);
            // Because value might change in the parent's setValue(), refresh it
            value = this.getValue();
            var fieldEl = this.fieldEl;
            if (this.constrain(value) === this.minValue) {
            else {

    Thanks for this fix. I noticed this yesterday after returning "false" from a validation on beforechange. Was getting frustrated.
