Passing an OBJECT between PORTLETS?

I can pass a simple parameter string all day long, underwater, while tapping my head.

What I can’t do is pass an object (attribute) between portlets. Is this possible?

Alternatively, is it possible to share an object between portlets?

I tried adding a bean to one portlet and shareing it with another, but it seems each portlet instansiates it’s own bean rather than shareing them.

Any help, as always, is very much appreciated!
