Web Dynpro and EP6 portal navigation / eventing requirements

What are the EP6 portal requirements for the portal eventing and portal navigation features?

I have followed the Howto and succesfully created web dynpro iViews of my components. However, when I try to use the Portal Eventing API or the Portal Navigation API, absolutely nothing happens. I noticed that there is a disclaimer in the Portal Eventing document that this is for 6.30. What does this mean?

I am running EP 6.0.2.3.2 [ 60_SP2P3_REL ] on one machine and WAS 6.40 preview on another. They are both on the same domain. The EP6 portal is running on top of J2EE Engine 6.20.
