Error when accessing a JSF portlet via WSRP

[carlo9890]

When I try to access a portlet that uses JSF via WSRP I get a NPE in RenderResponseImpl.getNamespace(RenderResponseImpl.java:134)

The problem can be reproduced:
Download the HelloWorldJSFPortlet application from portlet swap
Add a jboss-portlet.xml to make the portlet remoteable

<portlet-app>
<portlet>
<portlet-name>HelloWorldJSFPortlet</portlet-name>
<remotable>true</remotable>
</portlet>
</portlet-app>

Now deploy the app and create an instance of it using the "self" portlet provider
Add the portlet instance to a page and try to view it in your browser
The following exception should occur

Did anyone know what I do wrong here or is it a JBoss Portal bug??

[mrostan]

I'm having the same problem, I cannot access a JSF portlet remotely using WSRP.
Did anyone now something about it?

Thanks in advance

I also experienced the same problem but figured that since the NullPointerException is thrown when creating a uniqueId for a JSF component with no id the solution would be to have all jsf components set the id attribute explicitely. And this worked.

I think that the Namespace is null because of some still missing functionality in the code (the unique id is based on something (don´t remember what right now) that has to be provided by the consumer.

Looking at it. There's indeed a problem with the namespace. Thanks for the report.

This problem has now been fixed in the latest revision of Portal in subversion.
