onTriggerClick in the TriggerFieldAppearance is never fired.
We're working to build our own appearance to match our standard look and feel. While working on the ComboBox, we have not been able to find any way to get the onTriggerClick method of our TriggerAppearance to ever fire. We need to change the style of the trigger button when the button is clicked. Is this method being called? If so, where?
