Missing windowId for portlets events test

[rpa_rio]

Hi!

I'm trying to develop some portlets to test events on portletcontainer 2.0, when I try to perform an action on my sender portlet I get exception below:

java.lang.NullPointerException
at org.jboss.portal.portlet.controller.PortletRequestHandler.invoke(PortletRequestHandler.java:219)
at org.jboss.portal.portlet.controller.PortletRequestHandler.invoke(PortletRequestHandler.java:61)

it looks like a bug. can you describe the interactions you do ?

the controller package has been improved since the beta1 and is more robust, you could try SVN or wait for the next release.

I wrote two pages publisher-view.jsp and listener-view.jsp, in publisher-view.jsp I used portlet tags to generate the actionURL, exactly like we have below:

<%@ page contentType="text/html"%>
<%@ taglib uri="http://java.sun.com/portlet" prefix="portlet" %>
<portlet:defineObjects />
<portlet:actionURL var="submitUrl" portletMode="view" />
<div>
 <br />
 <br />
 <center>
 <form action="<%=submitUrl%>" method="post">
 <label for="input">Type your text:</label>
 <input type="text" id="input" name="input" value="" />
 <input type="submit" value="Send" />
 </form>
 </center>
</div>

When the submit button is clicked the processAction on PublisherPortlet must be invoked and then the event is set:

package br.eti.faces.portlet.publisher;

import java.io.IOException;

import javax.portlet.ActionRequest;
import javax.portlet.ActionResponse;
import javax.portlet.GenericPortlet;
import javax.portlet.PortletContext;
import javax.portlet.PortletException;
import javax.portlet.PortletRequestDispatcher;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;

import br.eti.faces.portlet.events.Literal;

public class PublisherPortlet extends GenericPortlet {

 @Override
 protected void doView(RenderRequest renderRequest,
 RenderResponse renderResponse) throws PortletException, IOException {

 renderResponse.setContentType("text/html");

 PortletContext ctx = getPortletContext();
 PortletRequestDispatcher dispatcher = ctx
 .getRequestDispatcher("/publisher-view.jsp");

 dispatcher.include(renderRequest, renderResponse);
 }

 @Override
 public void processAction(ActionRequest actionRequest,
 ActionResponse actionResponse) throws PortletException, IOException {
 String value = actionRequest.getParameter("input");
 actionResponse.setEvent(Literal.QNAME, new Literal(value));
 }

}

I defined this class as my event class:

package br.eti.faces.portlet.events;

import java.io.Serializable;

import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.namespace.QName;

@XmlRootElement
public class Literal implements Serializable {

 public static final QName QNAME = new QName("urn:jboss:portal:samples:event" , "Literal");

 private String data;

 public Literal(String data) {
 this.data = data;
 }

 public String getData() {
 return data;
 }

 public void setData(String data) {
 this.data = data;
 }
}

Finally, I registered both (porlet and event) on portlet.xml:

I used the demo3.jsp code and made minimal changes, now everything works ok.
