    Webcenter Portal 11.1.1.8 - java.lang.IllegalArgumentException: Panel oracle.adfinternal.pageeditor.pane.blank-panel not defined

    Harish Pothuri

      Hi,

       

      I have deployed a Webcenter Custom Portal app on weblogic server. When I stop it and start it from weblogic console and try to access the portal home page, it gives below exception :

       

      **javax.el.ELException: java.lang.IllegalArgumentException: Panel oracle.adfinternal.pageeditor.pane.blank-panel not defined.**

       

      It is giving problem only after stop and start the application. And I need to stop and start the webcenter portal app in order to make changes in shared lib whose reference is being used in webcenter portal. But everytime I stop and start the portal app, and open the home page it throws the exception.

       

      Part of exception trace is given below:
