Kent Tong commented on WICKET-1132:
-----------------------------------
I've created a ServletContextProvider for liferay using inspection, without any
reference to the liferay portal implementation classes:
package test;
import javax.portlet.GenericPortlet;
import javax.portlet.PortletRequest;
import javax.portlet.PortletResponse;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.portals.bridges.common.ServletContextProvider;
public class MyServletContextProvider implements ServletContextProvider {
public ServletContext getServletContext(GenericPortlet portlet) {
return (ServletContext) callMethod(portlet.getPortletContext(),
"getServletContext");
}
private Object callMethod(Object obj, String methodName) {
try {
return obj.getClass().getMethod(methodName).invoke(obj);
} catch (Exception e) {
throw new RuntimeException(e);
}
}
public HttpServletRequest getHttpServletRequest(GenericPortlet portlet,
PortletRequest portletRequest) {
return (HttpServletRequest) callMethod(portletRequest,
"getHttpServletRequest");
}
public HttpServletResponse getHttpServletResponse(GenericPortlet
portlet,
PortletResponse portletResponse) {
return (HttpServletResponse) callMethod(portletResponse,
"getHttpServletResponse");
}
}
However, when a form in the portlet is submitted, I get a NullPointerException
in WebResponse.write(WebResponse.java:355).
The issue is that the Wicket portlet code thinks the request is an action
request but Wicket is closing the response writer.
The HTTP request as view in WicketFilter.java is:
[method = POST, protocol = HTTP/1.1, requestURL =
http://localhost:8080/c/portal/layout, contentType =
application/x-www-form-urlencoded, contentLength = 46, contextPath = /portlet3,
pathInfo = null, requestURI = /portlet3/app/, servletPath = /app,
pathTranslated =
/home/kent/liferay-portal-tomcat-6.0-5.1.1/webapps/ROOT/guest/home]
The stack trace is here:
request.get1651409 [http-8080-2] ERROR

> Liferay portlet support
> -----------------------
>
> Key: WICKET-1132
> URL: https://issues.apache.org/jira/browse/WICKET-1132
> Project: Wicket
> Issue Type: Bug
> Components: wicket-portlet
> Affects Versions: 1.3.0-beta4
> Environment: Liferay 4.3.3 on Tomcat 6
> Reporter: Thijs Vonk
> Assignee: Ate Douma
> Attachments: patch-jira-wicket-1132.patch
>
>
> I created 2 simple Links a AjaxLink and a 'normal' link in a portlet. I
> deployed this portlet on Liferay. The normal link works fine. But the Ajax
> links doesn't work. In the generated HTML the url's look like this.
> AJAX link:
> <a href="#" wicket:id="link" onclick="var
> wcall=wicketAjaxGet('http://localhost:8080/web/guest/admin?p_p_id=MiniPortlet&p_p_action=1&p_p_col_id=column-1&p_p_col_count=1&;',null,null,
> function() {return Wicket.$$(this)}.bind(this));return !wcall;"
> id="id__MiniPortlet__WAR__MiniPortlet1____link1">
> Normal link:
> <a
> href="http://localhost:8080/web/guest/admin?p_p_id=MiniPortlet_WAR_MiniPortlet1&p_p_action=1&p_p_state=normal&p_p_mode=view&p_p_col_id=column-1&p_p_col_count=1&_MiniPortlet_WAR_MiniPortlet1__wu=%2Fminiportlet%2F%3Fwicket%3Ainterface%3D%3A0%3Alink2%3A%3AILinkListener%3A%3A";
> wicket:id="link2">
> At this moment the p_p_id is the part that I'm looking into. As you can see
> they are different. And for Liferay this part tels it which portlet it should
> send the request to. The normal link is the correct path to the portlet. as
> this action actually works.
