I have done the following renaming that will affect versions of JBPC after 2.0.0.CR2: WindowNavigationalState -> PortletWindowNavigationalState PageNavigationalState -> PortletPageNavigationalState Event -> PortletWindowEvent the reason is that those term were not precise enough and are conflicting with terms in 2.7 core. JBoss Portal 2.7 WindowNavigationalState is more broad and PortletWindowNavigationalState of JBPC controller is window navigational state for a portlet window. Note that renaming can easily be done with Idea which has a function to migrate class names. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4143862#...
