NullPointerException in IPCPhaseListener.afterPhase when accessing portlet

[Peter Szűcs, modifié il y a 10 années.]

Hi,

I have a portlet where I display a jsf composite element from another maven project that I depend on. Deployment goes without any exceptions but when I try to access the page with the portlet I get the following exception:

I'm using Liferay portal 6.2-ce-ga2 on JBoss 7.1.1 I upgraded a couple of modules to be able to use cdi and followed the tutorial for cdi portlet development. At the moment I can't run the server in debug mode and I haven't found much information on this exception on the internet so I only have a stack trace message right now. Could you suggest something to look into?

[Neil Griffin, modifié il y a 10 années.]

This is the line in the stacktrace that is the problem:

 8    at javax.faces.webapp.FacesServlet.service(FacesServlet.java:593) [jsf-api-2.1.21.jar:2.1]

In a portlet environment, the FacesServlet should never be hit directly by a request from the browser. Instead, all requests should go through the JSF Portlet Bridge. So I would recommend that you examine the request in Chrome to find out the URL that is being requested.

[Peter Szűcs, modifié il y a 10 années.]

Ah I see. It wasn't originally designed to run inside a portlet. After taking the corresponding servletmapping out of the web.xml it went without such exceptions.

Hi Peter,

I'm glad to hear that it is working for you now. Thanks for using Liferay Faces
