0. Introduction After struggling about for some days, I noticed that documentation has to be read! (Evidently) But this documentation needs some revision, spacially what matters Dialog Framework. I have forgotten to enclose this code in my faces-config.xml file! <application> <action-listener> org.primefaces.application.DialogActionListener </action-listener> <navigation-handler> org.primefaces.application.DialogNavigationHandler </navigation-handler> <view-handler> org.primefaces.application.DialogViewHandler </view-handler> </application> Now everything works as scheduled when copying the Primeface code in the Primefaces Show . This is a beginner's error! Sorry and happy coding!
