Hi, sorry but I forgott to post the Select bean class.
package jsf.beans;
import javax.faces.model.SelectItem;
public class Select extends SelectItem {
private String team1;
private String team2;
private String team3;
public Select(String v,String l){
super(v,l);
}
public String getTeam1() {
return team1;
}
public void setTeam1(String team1) {
this.team1 = team1;
}
public String getTeam2() {
return team2;
}
public void setTeam2(String team2) {
this.team2 = team2;
}
public String getTeam3() {
return team3;
}
public void setTeam3(String team3) {
this.team3 = team3;
}
}
As you can see this class extends from SelectItem class so theoretically i
have implemented a List of SelectedItems.
Thanks.
