        Hi,

        we are getting the following error:

        ERROR 06-18 07:44:19.875 o.a.w.DefaultExceptionMapper:170
        [nio-5443-exec-2] - Unexpected error occurred
        org.apache.wicket.WicketRuntimeException: Error attaching
        this container
        for rendering: [WebMarkupContainer [Component id = list]]

        I am assuming there is db modification for the customized
        menu, what is
        for upgrading please?

        Ali
