Hi,

you have to define a all_meta_types-method in your Class, which should 
return the allowed meta_types. Something like this should do it:

     def all_meta_types(self):
         ''' '''
         mt = []

         allowed_meta_types=('DTML Document','Folder','File')

         for meta_type in Folder.all_meta_types(self):
             if meta_type['name'] in allowed_meta_types:
                 mt.append(meta_type)

         return mt


Cheers, Maik
