    Error messages not being displayed

    Chris Mathrusse Newbie

      I'm using RichFaces 4 M5 and seem to have no issues rendering error messages that are associated to components. (validation, etc...)

       

      The problem I run into is when I when I raise an error from my backing bean, the message simply disappears. I see the error generated in the log file but no warnings about it unable to be displayed.

       

      My backing bean is as follows:

       

                public String calculate() {

            String msg = MessageUtils.getString("error.invalidSelection");

            logger.severe(msg);

            FacesMessage message = new FacesMessage(msg, msg);

            message.setSeverity(FacesMessage.SEVERITY_ERROR);

            FacesContext.getCurrentInstance().addMessage(null, message);

            return "failure";

                          }

       

      I don't have any navigation-rule configured for the "failure" outcome so no redirect is occurring.

       

      My xhtml page has the following:

       

        <ui:define name="content">

        <h:form id="request-form"> 

       

        <h:panelGrid>

                      <iii:welcome-message/>

       

                      <h:messages style="color:red"/> 

       

      So why isn't the FacesMessage appearing after the method returns?

       

      Thanks for the help...

          1) Try to wrap your h:messages into a4j:outputPanel. Because when you are using ajax re-rendering your h:messages may not be re-rendred with other elements.

          2) If your message should be displayed after the navigation or a4j:outputPanel does not work for you, post your code, please.

            Thank you for you assistance Ilya. Unfortunately the a4j:outputPanel did not resolve the issue. So I tried a very simple page with nothing more that a button that calls a test backing bean and creates an Error message. But that too does not render. So I've attached my code in hopes that you can identify what it is that I am doing incorrectly.

              1) h:messages won't be re-rendered without a4j:outputPanel or without re-rendering a parent tag for h:messages.

              Like this:

              a4j:commandButton render="wrap"

              <h:panelGroup id="wrap">

                   h:messages

              </...>

              2) Only as a matter of interest try to assign a message to particular element on form by id. And see if won't work.

                Adding the following:

                 

                              <h:panelGroup id="global-messages">

                                    <h:messages style="color:red" globalOnly="true"/>

                              </h:panelGroup>

                 

                <a4j:commandButton id="get-estimate-submit" render="global-messages"/>

                 

                Resolved the issue. I can now display the global messages. And pertaining to assigning a message to a particular element id, that seemed to work with my ajax calls when I would specify a validator. I guess that is because the validator is supplied the component and each of my components on the page has an <h:message> associated with it. Those messages always render next to the component that they are associated with. The only issue I seemed to have was with the global messages but I guess that was due to the fact that I am using an <a4j:commandButton> rather than an <h:commandButton>.

                 

                Thank you so much for resolving my issue!!
