[Zope] problems creating a Contents management tab

[Max M]

If you want to limit what objects can be added to youer objectManager just
put this method in your class:

    def all_meta_types(self):
        """ What types can you add to this objectManager? """
        allowedMetaTypes = ('DTML Method', 'DTML Document')
        result = []
        for metaType in Products.meta_types:
            if metaType['name'] in allowedMetaTypes:
                result.append(metaType)
        return result

It does it the "correct" way.
