I am really impressed with the Cocoon Forms framework!!

Many thanks guys!
Sorry, but I haven't got what you mean with "The Continuation has
completed". When is this event reached? Can you give a
example (maybe
using some code)?
This is what I am thinking about:

If you take this code snippet here:

   . . .
    // get the User
    form.load (user);
    session.close();
    form.showForm (formURI);
    session = factory.createSession ();
    form.save (user);
    // save the User
   . . .
The line "session.close();" in the sample above, could be replaced by
this (obviously after the snippet):
        catch (break) {
                session.close();
        }
because it will be called just as a continuation is about to start

whereas the line "session = factory.createSession ();" does
not have an
equivalent handler that would trigger after all continuation handling
has completed.
IIU Sylvain's docs correctly
(http://wiki.cocoondev.org/Wiki.jsp?page=RhinoWithContinuations)
catch (continue) {
   session = factory.createSession ();
}
should do it. Doesn't it work for you (I haven't tried it yet.)?
it works fine .... but I think it has a different meaning .... it is 
when an existing continuation is resumed ... ie. when a Request comes 
back to a continuation-id.

Whereas what I was thinking about is being notifies of when the 
continuation-cycle is complete and the continuation is disposed of.

If not you'll have to wait for my interceptions implementation 
(<hint>or
help me finishing it <hint/> ;-) which would fill this gap.
Currently I haven't much time doing it (but hopefully things change in
the next weeks - expect more work on this then).
Cool :)
