[Zope3-Users] Problems with "form" package and widget

[Paolo Cilmo]

 Hi!
 I'm tryng to create in Zope3 a "select tag" with this code:
         voc=SimpleVocabulary.fromValues(lst)
         repository_choice=Choice(title=u'Repository',
                     vocabulary='voc')
         repository_list=List(__name__='replist', title=u'Repositories',
                      description=u'The repositories',
                      value_type=repository_choice)
         field = Int(__name__='numero', title=u'Numero', min=0, max=10)
         request = TestRequest(form={'repository_list.replist': u'9'})
         widget = SelectWidget(repository_list, request)
         widget.hasInput()
         widget.getInputValue()
         a= widget().replace(' ', '\n  ')
         print a
 
 n.b. lst is a generic list
 
 but it take this error:
 __init__() takes exactly 4 arguments (3 given) How i correct this code?
 And, where i can find a GOOD document for using widget? Zope3 book is very bad...
 Please help me
