Viele Felder mit deforms

Hallo,

wenn ich viele Felder mit deform darstellen möchte (ab 20) bekomme ich
ein Fehler:

  Module zope.tales.tales, line 696, in evaluate

IndexError: list index out of range

Vieleicht hat jemand sowas schon mal gesehen.

Der code sieht so  aus:

class MySchema(MappingSchema):

    name = SchemaNode(String(),
                      description = LONG_DESC)
    title = SchemaNode(String(),
                      description = LONG_DESC)
    root = SchemaNode(String(),
                      description = LONG_DESC)
   .....viele viele felde


......
class DEformTest(BrowserPage):
    def form_view(obj):
        myform = Form(schema, buttons=('submit','clear'))
        return myform.render()
    __call__ = ViewPageTemplateFile('deform_test.pt')


Mit wenigen Feldern funktioniert es.
