Here is my SelectOneMenu
<h:selectOneMenu value="#{bean.myObject}" >
<f:ajax render="componentToRender" listener="#{bean.onSelect}"/>
<f:converter converterId="myObjectConverter" />
<f:selectItem itemLabel="None" itemValue="#{null}" />
<f:selectItems value="#{bean.objects}" var="object" itemValue="#{object}" itemLabel="#{object.name}" />
</h:selectOneMenu>
And my converter
@FacesConverter("myObjectConverter")
public class MyObjectConverter implements Converter{
private List<MyObject> objects;
public MyObjectConverter(){
this.objects = MyController.getAllMyObjects();
}
public Object getAsObject(FacesContext context, UIComponent component, String value) {
if(!StringUtils.isInteger(value)) {
return null;
}
return this.getMyObject(value);
}
public String getAsString(FacesContext context, UIComponent component, Object value) {
if(value == null) {
return null;
}
return String.valueOf(((MyObject) value).getId()).toString();
}
public MyObject getMyObject(String id) {
Iterator<MyObject > iterator = this.objects.iterator();
while(iterator.hasNext()) {
MyObject object = iterator.next();
if(object.getId() == Integer.valueOf(id).intValue()) {
return object;
}
}
return null;
}
}
The problem is that my ajax listener is never called and my component never rendered. Is there something wrong with my converter or selectOneMenu? I follow an example and I can't figure the mistake out.
BTW : my simple method in the bean
public void onSelect() {
System.out.println(this.myObject);
if(this.myObject != null) {
System.out.println(this.myObject.getName());
}
}
I already had a problem like this and I changed my selected value from object to id. But here I want to make it work with objects because I know it's possible.
Thanks
I have the solution. I had to override the "equals" method in MyObject class!
Thanks.
EDIT: the code
@Override
public boolean equals(Object obj) {
if(this.id == ((MyObject) obj).id) {
return true;
}else {
return false;
}
}
