    Problem with Seam mail

    Robin Newbie

      Im trying to send an email from an asynchronous method.

      @Asynchronous
      public QuartzTriggerHandle scheduleRaffle(@Expiration Date endDate, Season season, int raffleNo) {
      
       List<Subscription> winners = raffle2(season, raffleNo);
      
       try {
       Contexts.getEventContext().set("winner", winners.get(0));
       Subscription test = (Subscription)Contexts.getEventContext().get("winner");
      
       log.debug("###event context " + test.getEmail());
       renderer.render("/email/winner.xhtml");
       log.debug("Email sent successfully");
      
       } catch (Exception e) {
       log.debug("Email sending failed: " + e.getMessage());
       e.printStackTrace();
       }
      


      I see from my debug message that the winner variable is set correctly in the context.

      <ui:composition xmlns="http://www.w3.org/1999/xhtml"
       xmlns:ui="http://java.sun.com/jsf/facelets"
       xmlns:s="http://jboss.com/products/seam/taglib"
       xmlns:m="http://jboss.com/products/seam/mail"
       xmlns:h="http://java.sun.com/jsf/html"
       xmlns:f="http://java.sun.com/jsf/core">
       <m:message>
      
       <m:from name="test" address="my email address goes here" />
       <m:to name="test">my email address goes here</m:to>
       <m:subject>testing</m:subject>
      
       <m:body>
       <p><h:outputText value="Hej" />,#{winner.email}</p>
       <p>some more text</p>
       </m:body>
      
       </m:message>
      </ui:composition>
      


      If I remove #{winner.email} everything works fine but when it is there I get NPE.

      Some help would be very appreciated.
