Hello,

about PortletSession replication in clusters, the documentation says :

anonymous wrote : The servlet specification is very loose on the subject of replication and does not state anything about the replication of sessions during a dispatched request. JBoss Portal offers a portlet session replication mechanism that leverages the usage of the portal session instead which has several advantages :
| Replicate only the portlet that requires it.

any idea of what is meant by : "Replicate only the portlet that requires it."

I guess it means :
- only the portlet that have received the action request have changed its state
- so only this portlet session his replicated

is that correct ?
is it "several portlets sessions are replicated ?

more detail in the doc, on what is the criteria of "that requieres it" and on when and how it is done... would be nice.

because, there is another question :
- with the event feature, that allow to dispatch the request from one portlet to another (see documentation 2.6 / chapter 10.8.2. Achieving Inter Portlet Communication with the events mechanism)
- then, which portlet session(s) will be replicated ?

The global question is : can events be used widely in HA clustered mode ?

Open a jira for more details in this chapter of the doc ?
