I am using IPC in two JSF portlets to communicate one java class. I seem to be missing something and I am getting the following error ::
13:54:39,583 ERROR [IPCPhaseListener:301] null
java.lang.IllegalStateException

The changes i have done are the following ::
Portlet.xml ::
<portlet>
<portlet-name>Sender</portlet-name>
<supported-public-render-parameter>communicationBean</supported-public-render-parameter>
</portlet>
<portlet-name>Reciever</portlet-name>
<supported-public-render-parameter>communicationBean</supported-public-render-parameter>
<public-render-parameter>
<identifier>communicationBean</identifier>
<qname xmlns:x="http://liferay.com/pub-render-params">x:communicationBean</qname>
</public-render-parameter>
Faces-config.xml ::
<application>
<application-extension>
<bridge:public-parameter-mappings>
<bridge:public-parameter-mapping>
<parameter>Sender:communicationBean</parameter>
<model-el>#{senderManagedBean.communicationBean}</model-el>
</bridge:public-parameter-mapping>
<bridge:public-parameter-mapping>
<parameter>Reciever:communicationBean</parameter>
<model-el>#{recieverManagedBean.communicationBean}</model-el>
</bridge:public-parameter-mapping>
</bridge:public-parameter-mappings>
</application-extension>
</application>
Is there something that I am missing in this?
I saw this exactly from the demo given in website and it looks quite simple and should work? is there any more configuration required? or is it because i am passing a class that it is failing?
