             Summary: Including h:head breaks f:ajax events of commandButton
                 Key: RF-12003
                 URL: https://issues.jboss.org/browse/RF-12003
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: base functionality 
    Affects Versions: 4.2.0.CR1, 4.1.0.Final
         Environment: JBoss 7.0.2 Final, JBoss 7.1.0 Final, RichFaces 4.2.0 Final, 4.1.0 Final, Chrome and Safari
            Reporter: Joern Ohmen
            Priority: Critical

If I add h:head-Tag to my page, the ajax events of the h:commandButton are not working. The example should show up a panel with a click on a button, but nothing happens. The example is working when h:head is removed. I use a ConversationScoped Bean.
