We can also fire an event for an anonymous user using portlet wiring. To get that property we are supposed to do following changes inside  WAS ->

Resources -> Resource Environment Providers:

WP PortletServiceRegistryService -> Custom Properties:
we need to have the property "com.ibm.wps.propertybroker.standard.service.PropertyBrokerServiceWrapper.com.ibm.portal.propertybroker.standard.anonymous.page.support" set to "true".
