what Bas said .. also i think it will be better to load data lazily instead
of using listener for performance ,pseudocode below
just call LazyLoad.getData(cycle,mailId) when there is a need ..
public class LazyLoad implements Serializable{
public static final MetaDataKey<UserData> KEY= new
MetaDataKey<UserData>() {};
public static UserData getData(RequestCycle cycle,String mailId){
UserData data=cycle.getMetaData(KEY);
if(data!=null){
return data;
}
data=service.loadData(mailId) ;
cycle.setMetaData(KEY,data );
return data;
}
}
