jboss-portletcontainer-2.0.0 with jbossas42 the art of resiz

[terroene]

Hello again,
One problem solved, another problem found:

What do I have to do to make a portlet resizable using the xportal-Taglib in jboss-portletcontainer-2.0.0??????????????????????????????????

I already searched in the simple-portal sources, but I found nothing but the realization that it doesn't have to do with the portlet-code. Perhaps I missed a configuration file.

If I click on a rezise-Button the following error occurs:

Please help,

One step forward:

The exception occurs in this method of class PagePortletControllerContext

 protected Portlet getPortlet(String windowId) throws PortletInvokerException
 {
 WindowDef windowDef = prepareResponse.getWindowDef(windowId);

 //this crashes with a NullpointerException:
 return findPortlet(windowDef.getApplicationName(), windowDef.getPortletName());
 }

//find portlets:
public Portlet findPortlet(String applicationName, String portletName)
 {
 return portlets.get(new Key(applicationName, portletName));
 }

How can I make an entry in the portlets-Map?????
Either the application name or the portletName seems to be null.

Oh, I forgot:
The Map is filled by this foreach-statement:

 Map<Key, Portlet> portlets = new HashMap<Key, Portlet>();
 for (Portlet portlet : invoker.getPortlets())
 {
 PortletInfo portletInfo = portlet.getInfo();
 String portletName = portletInfo.getName();
 String applicationName = portletInfo.getApplicationName();
 Key key = new Key(applicationName, portletName);
 portlets.put(key, portlet);
 }

So I have to tell the invoker of type PortletInvoker to add my portlet/application, how can I do this?

If this:

return findPortlet(windowDef.getApplicationName(), windowDef.getPortletName());

fails with a NPE, it means that *windowDef* is null

[terroene]

How can I provide a value for "windowDef"??????

The jsps in the demo folder use the same markup like I do (my code):

<%@ page contentType="text/html" %>
<%@ page language="java" %>
<%@ taglib prefix="xportal" tagdir="/WEB-INF/tags/portal" %>
<%@ taglib uri="/WEB-INF/portal.tld" prefix="portal" %>
<%@ page isELIgnored="false" %>


<%@ include file="/layouts/header.jsp" %>
<link rel="stylesheet" href="${pageContext.request.contextPath}/css/debugger.css" type="text/css"/>
<script type="text/javascript" src="${pageContext.request.contextPath}/js/debugger.js"></script>
<portal:page>
 <xportal:1column>
 <jsp:attribute name="leftcol">
 <xportal:portlet name="Kundensuche" applicationName="PortletShell" id="Kundensuche"/>
 </jsp:attribute>
 </xportal:1column>
</portal:page>
<%@ include file="/layouts/footer.jsp" %>

Sorry,but is this so difficult to answer?
Seems to me like a configuration problem,
please answer.

Problem solved:

The page containing my portlet is the welcome-page, so the page-name is not provided, e.g. "http://localhost:8080/MyApp".

Resizing works if you use "http://localhost:8080/MyApp/Pagename.jsp".
