By checking the registry for all adapters registered.

 from zope.component import queryAdapter

queryAdapter(object, interface) ... # check the syntax and make sure you  
have the registry loaded.

The transactional stuff does not happen in zope.formlib. Unfortunately  
zope.formlib is a bit opaque in the way it works.

Which is why you should let the library handle this for you wherever  
possible and something you write tests for.
