    Seam Mail and IceFaces: Problem with Renderer

    Christoph Kraus Newbie

      Dear all,


      I use seam 2.2.0GA with icefaces 1.8.2 on a jboss server to send emails and it works (nearly) perfect.
      The problem is that if I try to send an email for the first time after rendering the view, I get a NullPointerException thrown after calling the renderer.render(). Every following click on the 'send email' button sends emails as expected.


      Here is the method that renders my mail template:


      @In(create = true)
      private Renderer renderer;
      
      public void sendMail(Mail mail)
      {
          try
          {
              currentMail = mail;
              renderer.render("/system/MailTemplate.xhtml");
              facesMessages.add("Email sent successfully");
          }
          catch(Exception e)
          {
              facesMessages.add("Email sending failed: " + e);
          }
      }
      



      Here is my mail template:


      <m:message xmlns:m="http://jboss.com/products/seam/mail"
                 xmlns:ui="http://java.sun.com/jsf/facelets"
                 importance="high">
          <m:from name="#{currentMail.from.firstname} #{currentMail.from.lastname}"
                  address="#{currentMail.from.email}"/>
          <m:to name="#{currentMail.to.firstname} #{currentMail.to.lastname}" address="#{currentMail.to.email}"/>
          <ui:repeat var="_receiver" value="#{currentMail.ccReceivers}">
              <m:cc name="#{_receiver.firstname} #{_receiver.lastname}" address="#{_receiver.email}"/>
          </ui:repeat>
          <m:subject>#{currentMail.subject}</m:subject>
          <m:body>
              <html>
              <body>
              <p>Dear #{currentMail.to.firstname} #{currentMail.to.lastname},</p>
              <p/>
              <p>#{currentMail.body}</p>
              <p>#{currentMail.optionalBody ne null ? currentMail.optionalBody : ''}</p>
              <p/>
              <p>Best regards,</p>
              #{currentMail.from.firstname} #{currentMail.from.lastname}
              </body>
              </html>
          </m:body>
      </m:message>
      



      I tried to send the email synchronous as well as asynchonous, but both methods ended in a NullPointerException. I hope anyone can think of my problem.


      Many thanks in advance,
      Chris

          Debug it to see where it fails or at least post the stack trace.

            </faces-config>
            



            I think the configuration is ok because rendering PDFs or Excelsheets works correct.
            I checked if the renderer is NULL, but he isn't.
            I jumped through the code, to see what happens after calling the renderer.render(/system/MailTemplate). After initializing a org.jboss.seam.ui.facelet.RendererRequest object, the run() method is called.
            Everything works fine... The renderFacelet is called and the facesContext is released and cleaned up. I really don't know, why and where the NullPointerException is thrown, because everything seems to work like expected.
            I really hope you can help me...
