Hi,
Sorry, but I did not read the post carefully enough. Yes, in order for two
portlets to communicate (pass data), you need to use either public render
parameters or portlet events. The
javax.portlet.actionScopedRequestAttributes container runtime option can be
used by a single portlet to pass request attribute data from the
processAction() method to the processEvent() or render() methods. It cannot
be used for interportlet communication.

technically, you should only use public render parameters or events to
share state between portlets. Though using the PortletRequest might work
in Pluto it is not standard and you wil lfind that this won't work on many
portlet containers. You can rely on the PortletSession however you must
put the data in APPLICATION_SCOPE not PORTLET_SCOPE (the default) if you
want all portlets in the same web application to see the attribute.

Eric,
The attributes need to be set on the PortletRequest, not the
PortletSession.

Subject: Pluto-2.0 portletSession cannot share parameters !!!
Hello,
I am testing the Pluto-2.0. I could not retrieve the attributes from
PortletSession.
For example,
I use portletSession.setAttribute("MYVAR", "some value") in
PortletA,
and retrieve it in PortletB, but it always returned "null".
I tried to add the following in the portlet.xml in application
level.
<container-runtime-option>
<name>javax.portlet.actionScopedRequestAttributes</name>
<value>true</value>
<value>numberOfCachedScopes</value>
<value>10</value>
</container-runtime-option>
Is there any bug ?
Best regards,
Eric
