    Wired component null in seam EntityHome action

    Hardik Mehta Newbie

      I have a custom EntityHome class. I wire the dependent entity in the wire method, but when I call the action (persist) the wired component is always null.


      What could be the reason, similar code generated by seam gen is apparently working.


      Here is the entity class.


      I have overrden persist method to log the value of the wired element.


      @Name("roundHome")
      @Scope(ScopeType.CONVERSATION)
      public class RoundHome extends EntityHome<Round>{
      
          @In(required = false)
          private Golfer currentGolfer;
      
          @In(create = true)
          private TeeSetHome teeSetHome;
      
          @Override
          public String persist() {
              logger.info("Persist called");
              if (null != getInstance().getTeeSet() ) {
                  logger.info("teeSet not null in persist");
              } else {
                  logger.info("teeSet null in persist");
                  // wire();
              }
              String retVal =  super.persist();    //To change body of overridden methods use File | Settings | File Templates.
              return retVal;
          }
      
          @Logger
          private Log logger;
      
          public void wire() {
      
              logger.info("wire called");
              TeeSet teeSet = teeSetHome.getDefinedInstance();
      
      
              if (null != teeSet) {
                  getInstance().setTeeSet(teeSet);
                  logger.info("Successfully wired the teeSet instance with color: " + teeSet.getColor());
              }
          }
      
          public boolean isWired() {
              logger.info("is wired called");
              if(null == getInstance().getTeeSet()) {
                  logger.info("wired teeSet instance is null, the button will be disabled !");
                  return false;
              }
              else {
                  logger.info("wired teeSet instance is NOT null, the button will be enabled !");
                  logger.info("teeSet color: "+getInstance().getTeeSet().getColor());
                  return true;
              }
          }
      
          @RequestParameter
          public void setRoundId(Long id) {
              super.setId(id);
          }
      
          @Override
          protected Round createInstance() {
              Round round = super.createInstance();
              round.setGolfer(currentGolfer);
              round.setDate(new java.sql.Date(System.currentTimeMillis()));
              return round;
          }
      }
