Re: WSRP | Portlet Caching

Hi,
this is problem is related to navigational state. since the navigation state is
set to true and the same markup will be sent back when the remote portlet sent
for markup request.

What you can do:
Create a Interceptor and clear the navigational state in precise 
follow this steps.
1) create the navigational state interceptor
2) configure this interceptor in . go to merged view and copy the following file
in your web app
wsrp-consumer-handler-config.xml
