PickList PrimeFaces not working - jsf

Question

I try to use the pickList component of Primefaces. My converter does not work properly and I don't know why.
This is my ManagedBean:
#ManagedBean(name = "comMB")
#SessionScoped
public class TeamCompetitionBean implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
private DualListModel<Team> teams;
List<Team> source;
List<Team> source1;
List<Team> target;
#ManagedProperty("#{team}")
private TeamServiceI teamService;
List<String> teamNameList ;
// public TeamCompetitionBean() {
public DualListModel<Team> getTeams() {
// Players
teamNameList = new ArrayList<String>();
source = new ArrayList<Team>();
target = new ArrayList<Team>();
source.addAll(getTeamService().getTeam());
teams = new DualListModel<Team>(source, target);
return teams;
}
public void setTeams(DualListModel<Team> teams) {
this.teams = teams;
}
public void onTransfer(TransferEvent event) {
StringBuilder builder = new StringBuilder();
for (Object item : event.getItems()) {
builder.append(((Team) item).getTeamName()).append("<br />");
}
FacesMessage msg = new FacesMessage();
msg.setSeverity(FacesMessage.SEVERITY_INFO);
msg.setSummary("Items Transferred");
msg.setDetail(builder.toString());
FacesContext.getCurrentInstance().addMessage(null, msg);
}
public TeamServiceI getTeamService() {
return teamService;
}
public void setTeamService(TeamServiceI teamService) {
this.teamService = teamService;
}
public List<Team> getSource() {
return source;
}
public void setSource(List<Team> source) {
this.source = source;
}
public List<Team> getTarget() {
return target;
}
public void setTarget(List<Team> target) {
this.target = target;
}
public void afficher(){
System.out.println(target);
System.out.println(source);
}
}
and this is my entity class that I would like to load in my pickList:
#Entity
#Table(name = "team", catalog = "competition_manager")
public class Team implements java.io.Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
private Integer idTeam;
private Stadium stadium;
private League league;
private String teamName;
// getters and setters
#Override
public String toString() {
return teamName.toString();
}
#Override
public boolean equals(Object obj) {
if (!(obj instanceof Team)) {
return false;
}
Team f = (Team) obj;
return (this.idTeam == f.getIdTeam());
}
Now, this is my custom Converter:
#FacesConverter(forClass = Team.class, value = "teamConverter")
public class TeamConverter implements Converter {
Team team;
public Object getAsObject(FacesContext facesContext, UIComponent component,
String value) {
System.out.println("hello object");
if (value == null || value.length() == 0) {
return null;
}
ApplicationContext ctx = FacesContextUtils
.getWebApplicationContext(FacesContext.getCurrentInstance());
TeamBean controller = (TeamBean) ctx.getBean("teamMB");
List<Team> liststagiaire = controller.getTeamList();
for (int i = 0; i < liststagiaire.size(); i++)
{
team = liststagiaire.get(i);
if (team.getIdTeam() == getKey(value)) {
break;
}
}
return team;
}
java.lang.Integer getKey(String value) {
java.lang.Integer key;
key = Integer.valueOf(value);
return key;
}
String getStringKey(java.lang.Integer value) {
StringBuffer sb = new StringBuffer();
sb.append(value);
return sb.toString();
}
public String getAsString(FacesContext facesContext, UIComponent component,
Object object) {
System.out.println("hello string");
if (object == null) {
System.out.println("hello string null");
return null;
}
if (object instanceof Team) {
System.out.println("hello string intance of");
Team o = (Team) object;
String i = getStringKey(o.getIdTeam());
return i;
} else {
System.out.println("hello throw");
throw new IllegalArgumentException("object " + object
+ " is of type " + object.getClass().getName()
+ "; expected type: " + Team.class.getName());
}
}
}
And finally this is my XHTML page:
<p:pickList id="teamPickList" value="#{comMB.teams}" var="team"
itemValue="#{team}" itemLabel="#{team}" converter="teamConverter">
</p:pickList>

Your problem is comming from this line (in your class TeamConverter) :
if (team.getIdTeam() == getKey(value)) {
You can't compare Integer objects like that, because doing like this you are comparing reference. You should replace this line by
if (team.getIdTeam().intValue() == getKey(value).intValue()) {
You have the same problem in your class Team :
return (this.idTeam == f.getIdTeam());
should be replaced by :
return (this.idTeam.intValue() == f.getIdTeam().intValue());
Not related :
You don't need to use getKey and getStringKey, you could replace them simply like this :
getKey(value) // this
Integer.valueOf(value) // by this
and
getStringKey(o.getIdTeam()) // this
o.getIdTeam().toString() // by this
Also you should replace itemLabel="#{team}" by itemLabel="#{team.teamName}" in your view.
