MCheckBox does not respond to FormPanel.reset()

What steps will reproduce the problem?

1. Wrap a MCheckBox with a FormPanel
2. change the state of MCheckBox 
2. Call FormPanel.reset()
3. MCheckBox stays in the changed state

What is the expected output? What do you see instead?

MCheckBox should go to default value, instead the value does not change

What version of the product are you using? On what operating system?

m-gwt-1.1.2, developing under Windows 7, testing in Firefox Dev Mode and iPad 
Retina Super Dev Mode

Please provide any additional information below.

Well this is no big surprise since MCheckBox is not a real form element, which 
would be cleared on form.reset(). Unfortunately, the browser only notifies the 
form on reset, not the child elements so there is no chance to register for 
this event (yet). 

And more unfortunately, GWT does not support to add an event on form.reset(), 
but I created a feature request on that: 
https://code.google.com/p/google-web-toolkit/issues/detail?id=8215

Once this event handler is available in GWT, you could crawl up the widget 
hierarchy to see if the MCheckBox is wrapped by a FormPanel and register a 
reset event handler which resets the MCheckBox.

The background here is that I reuse my forms instead of creating new ones when 
the same activity shows a new set of data and calling FormPanel.reset() is a 
very convenient way of resetting the view, at least its form parts. For now I 
always need to reset MCheckBoxes separately. 

Since you are in the GWT steering committee this may be a good example for the 
reset event handler feature request :)

Thanks in advance!
