Description (last modified by )
Hi,
I found a problem with the onchange method of dijit.Form.CheckBox? and RadioButton?.
When the widgets are created programmatically the onchange method is fired twice. I didn't test it with markup.
Here under find a code that demonstrate the problem. This occurs with FF, IE6 and IE7, under Windows XP sp2.
Dojo version is 0.9.0dev (11363) major=0 minor=9 patch=0 flag=dev revision=11363

The problem is that ToggleButton? setChecked calls onChange directly w/o checking for actual change. Everything should be going thru setValue.

(In [11982]) Fixes #5222 !strict. Split out the special value processing in _FormWidget and subclassed it into _FormValueWidget so that Button and TextBox? could inherit from different classes, allowing value to be treated like a simple string attribute for Buttons/checkboxes and as complex objects for input widgets (dates/times/currency/etc). Deprecated setChecked and setValue for Button widgets (and subclasses) for the new setAttribute method for all simple attributes. Removed onChange(string) that was being called for Buttons/checkboxes when the value attribute was changed. Only onChange(boolean) should be called for checkboxes.

Hmm, it shouldn't be getting called at all (on instantiation). Doug, can you fix?
