ext.pylons - GenerationException: url_for could not generate URL. Called with args: () {'page': 2}

Hi All!

I use FormAlchemy-1.3 and WebHelpers-0.6.4

Why should I import "from formalchemy.ext.pylons import maps" does it needed?
When I set explicit=True at Mapper all models data that need paging throw
that error:

    forms = None

    def Session(self):
        return model.meta.Session

AdminController = ModelsController(AdminControllerBase,

    map = Mapper(directory=config['pylons.paths']['controllers'],

    map.minimization = False

    # The ErrorController route (handles 404/500 error pages); it should
    # likely stay at the top, ensuring it can always be resolved
    map.connect('/error/{action}', controller='error')
    map.connect('/error/{action}/{id}', controller='error')

    map.connect('admin', '/admin', controller='admin', action='models')
    map.resource('model', 'models', path_prefix='/admin/{model_name}',
controller='admin')

    map.connect('/{controller}/{action}')
    map.connect('/{controller}/{action}/{id}')

    return map
