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></name>
<value>true</value>
<value>CachedScopes</value>
<value>10</value>
</container-runtime-option>




Is there any bug ?

Best regards,
Eric




public class HelloWorldPortlet extends GenericPortlet {
public static final String VIEW_PAGE = "/WEB-INF/portlets/demo/view.jsp";


public void doView(RenderRequest request, RenderResponse response)
throws PortletException, IException {


//
// retrieve the
attribute from the portlet session
//
return NULL

System.out.println("" +
request.getPortletSession().getAttribute("MYVAR"));

response.setContentType("text/html");
PortletContext context = getPortletContext();
PortletRequestDispatcher requestDispatcher =
context.getRequestDispatcher(VIEW_PAGE);
requestDispatcher.include(request, response);

}
}








public class LocalePortlet extends GenericPortlet {
private static final String VIEW_PAGE =
"/";

private Log log = LogFactory.getLog(this.getClass());

public void doView(RenderRequest request, RenderResponse response)
throws PortletException, IException {
response.setContentType("text/html");


PortletContext context = getPortletContext();
PortletRequestDispatcher requestDispatcher = context
.getRequestDispatcher(VIEW_PAGE);
requestDispatcher.include(request, response);
}

public void processAction(ActionRequest request, ActionResponse response)
throws PortletException, IException {

//

// set attribute to
portlet session
//

request.getPortletSession().setAttribute("MYVAR", "This is my variable");
}

}

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

}

technically, you should only use public render parameters or events to share state between portlets.&nbsp; 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.&nbsp; 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.
