For the record, I believe the problem is that because disabled form elements do not get submitted with the form, submission of a disabled boolean checkbox is interpreted the same as an unchecked boolean checkbox -- so even though SQLFORM.__init__ creates the widget with _checked=True, the FORM.accepts method ultimately sets _checked=None.
