Hello All,
I am running the hello world faces portlet example using the MyFacesGenericPortlet class.
I changed the scope for my bean to request and updated the concatenateNames() method to
get the first and last name out of the context, but I am getting a class cast exception.
This worked fine when it was in the session scope. I am using
jboss-portal-2.2.1-SP2-bundled version of the portal. Please help.
Thanks,
Mark
faces-config.xml setting:
| <managed-bean-scope>request</managed-bean-scope>
