Hi Marion, the class side message of defaultSpec is generally meant to be used if you use a fixed number of widgets, so you can put the reference to the name of each widget there (in cour case #buttons). For variable number of widgets you should have a look at the dynamic features of Spec.
That being said, It looks like what you really want to use is a Radio Button Group. Have a look at RadioButtonGroupExample. HTH -- Does this mail seem too brief? Sorry for that, I don’t mean to be rude! Please see http://emailcharter.org .
