Description

Steps to reproduce:
1. Modify the BonjourMonde portlet from the Jetspeed 2.2.0 tutorial creating an action in which a render parameter is set on ActionResponse without changing window state, as in the following:
// Begin BonjourMonde.java
package org.apache.portals.tutorials;

import java.io.IOException;

import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import javax.portlet.GenericPortlet;
import javax.portlet.PortletException;
import javax.portlet.PortletURL;
import javax.portlet.ProcessAction;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;

public class BonjourMonde extends GenericPortlet {

@Override
protected void doView(RenderRequest request, RenderResponse response) throws PortletException, IOException

{ response.setContentType("text/html"); PortletURL url = response.createActionURL(); url.setParameter(ActionRequest.ACTION_NAME, "refresh"); response.getWriter().println("<form name=\"form" + response.getNamespace() + "\" method=\"post\" action=\"" + url.toString() + "\"/>"); response.getWriter().println("<b>Bonjour: View Mode</b>"); response.getWriter().println("<input type=\"submit\" value=\"Refresh\"/>"); response.getWriter().println("</form>"); }

@ProcessAction(name="refresh")
public void refreshAction(ActionRequest request, ActionResponse response) throws PortletException, IOException

{ response.setRenderParameter("some", "value"); }

}
// End BonjourMonde.java
2. Include above portlet in portal page and maximise the portlet
3. Invoking the "refresh" action will cause the portal page to resort to "normal" window state rendering whereby all portlets are rendered instead of only maximized one

This behaviour was not observed in Jetspeed 2.1.3 and would seem to violate the Portlet specification:
From JSR-286:
PLT.7.1.2 Including a Portlet Mode or a Window State

L38. If the window state is not set for a URL, it must have the
window state of the current request as defaultxlv
