Wired component null in seam EntityHome action
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;
}
}
