RE: Accessing PO session data from business objects

If I modify the signature of the save() method in a BO, then I would
have to change all the calls to this method in 10,000 places in the
presentation layer.
Instead, I decided to map each thread created by Enhydra with the
session it is currently associated with. I update this table every time
the run(HttpPresentationComms) method in HttpPresentation object is
called. I keep this global hash table around and access it from within
the business layer.
Does anyone see a problem with this approach?
Thanks.

Oleg

I think it is not possible.
You have to pass the HttpPresentationComms objekt 
which is only available in a PO
to the save - method.
(Or pass only the data you need in the save - method)

So the save - method should look like this: save(HttpPresentationComms
comms) or save(ClassYouNeed xyz)
