Is Spark suppose to render data forms sent by smack extensions?

The examples provided by Smack’‘s documentation seem to work fine on theclient that send s the data form message, but the client receiving the data form does not render any form. I am using Spark as the client receiving the form and Unit Tests as the client sending the form via Smack’‘s API. Is this the way it’'s suppose to work? If not which client is suppose to render these forms?
