After you add the Cooperative Portlet Source and Cooperative Portlet Target builders that add Property Broker or Click-to-Action functions to a model, you must republish the portlet WAR.
These builders describe target portlet actions using WSDL definitions, and these WSDL files must be added to the portlet WAR file. Republishing the portlet WAR will add these definitions to it. If the Publish Application function is not enabled in the project, manually update the portlet WAR with the Portal Server administration tool after republishing the portlet WAR.
