richfaces portlet bridge 3.1.2.GA - NullPointerException

[marcus21]

hello,
when I upgrade from richfaces-3.1.1.GA to richfaces-3.1.2.GA the according portlet bridge doesn't work.
I get a NullPointer-Exception - so I must go back on bridge-3.1.1.GA.
Is there a changed configuration necessary?
I use:
faces.config:

<application>
<view-handler>org.ajax4jsf.portlet.application.PortletViewHandler</view-handler>
<state-manager>org.ajax4jsf.portlet.application.PortalStateManager</state-manager>
<variable-resolver>org.springframework.web.jsf.DelegatingVariableResolver</variable-resolver>
</application>

<factory>
<faces-context-factory>org.ajax4jsf.portlet.context.FacesContextFactoryImpl</faces-context-factory>
</factory>

<managed-bean>
<managed-bean-name>ajaxContext</managed-bean-name>
<managed-bean-class>org.ajax4jsf.portlet.PortletAjaxContext</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>

<render-kit>

<renderer-class>
org.ajax4jsf.portlet.renderkit.portlet.PortletAjaxViewRootRenderer
</renderer-class>
</renderer>
</render-kit>

this is the Exception:

When I use the SNAPSHOT-Releases of richfaces and the portlet-bridge I get the same errors.

I use JBoss AS 4.2.1 with JSF-1.2 RI , Portal-2.6.2 and Facelets-Technology.

What can I do?
Is it possible to use richfaces + jsf-1.2RI and Portal-2.6.2 with JSP-technology instead of facelets-technology?

Thanks!

Hi Marcus,
I'm sorry, I have not a solution for you, but maybe you can help me.
I try to deploy my app with richfaces-3.1.1 GA on JBoss Portal 2.6 GA.
It seems you did it successfully.
My faces.config is almost the same than yours (I don't use Spring)
Can you show me your web.xml ?

Thanks for your help.
JP

OK, but not all richfaces components work.
It works:
- <rich:dataGrid />
- <rich:dataTable />
- <rich:datascroller />

I think the portlet-bridge actually has problems with the scope of components, for example the jsf-managed-beans.

I am trying to deploy a richfaces portlet not using Facelets - with no success -
http://jboss.com/index.html?module=bb&op=viewtopic&t=115083&postdays=0&postorder=asc&start=10

Does anyone succeded doing this?

Hi Marcus,
i'm in the same trouble, i tried also 3.1.3.CR3 without success.
I used pluto as portlet container and pit 3.1.0 i have no problem.
You have any news ?

[marcus21]

Hi,

the new Richfaces version 3.1.3 now works in Portal 2.6.3 and JBoss-4.2.x!
use the following libs:

richfaces-api-3.1.3.GA.jar
richfaces-impl-3.1.3.GA.jar
richfaces-ui-3.1.3.GA.jar

and use the bridge from Maven-Repo:
http://repository.jboss.com/maven2/org/richfaces/extensions/portletbridge/portletbridge-api/3.1.3.GA/
and
http://repository.jboss.com/maven2/org/richfaces/extensions/portletbridge/portletbridge-impl/3.1.3.GA/

portletbridge-api-3.1.3.GA.jar
portletbridge-impl-3.1.3.GA.jar

I use facelets-technology so my web.xml looks like:

Marcus, did the new portlet bridge(3.1.3) resolve the JSF bean scope issue for you?

I also used to use AjaxFacesPortlet directly, and put "org.ajax4jsf.portlet.PortletAjaxContext" in the "faces-config.xml", but it has issues with JSF managed bean session scope whenver I use Ajax4JSF. Does this issue sound familiar?

I spent quiet a bit time to use this new bridge, but facelets CompositionComponents aren't displayed anymore. No error, it just shows nothing in the portlet. My portal is liferay 43. I downloaded the portlet bridge from the link from your posted above. Also I did follow all the instructions about the config file tweaks. Does this ever ring a bell to you?

Any pointer will be greatly appreciated!!
