Action processing for maximized portlet which sets any render parameter on
ActionResponse without changing window state causes portal page to resort to
"normal" window state rendering whereby all portlets are rendered instead of
only maximized one
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Key: JS2-1046
URL: https://issues.apache.org/jira/browse/JS2-1046
Project: Jetspeed 2
Issue Type: Bug
Components: Aggregation
Affects Versions: 2.2.0
Environment: Windows XP
Java 5.0
Jetspeed 2.2.0/Tomcat 6.0.18 binary distribution
Reporter: Bernard Holland
Priority: Critical
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
