    Exception problem

    guy bashan Apprentice

      Hi, I am having an exception that I cannot figure out. I have a page backed by a bean, In the bean I have several propertis with getters and setters. When the page loads I am getting this exception:


      javax.faces.FacesException: javax.el.PropertyNotFoundException: /signup.xhtml @53,23 value="#{signup.password}": Property 'password' not found on type com.nikonians.ui.view.bean.SignupAction_$$_javassist_6

      I doubled checked and the property password is there as well as it's setters and getters. When I move the control from my page the exception moves to the next control binded to a property.


      Does anyway has a clue what it means?
      Thanks,
      Guy.

          if your JSF EL is like such:

          <h:outputText value="#{foo.bar}"/>

          then there must be a class annotated as such:

          @Name("foo")

          and there must be a public method as such (e.g. returns String for example):

          public String getBar() {
          ...
          }

          and also you'll need a local interface that the SFSB/SLSB implements with that method in it (if you're using EJB as backing bean).

          post your backing bean code...

            Hi,


            I have a bean named signup (using @Name), and I have a private member named password with public getter and setter. Isn't it enough for things to work. I have being working like this for several years with JSF only...


            I am not using EJB...


            This is my backing bean:



            @Name("signup")

              Try adding getPassword(), I don't see one.. or change you EL to:


              #{signup.passwordConfirm}
