Example
Executes the requests with the specified delay in milliseconds, meaning that if any subsequent request happens after the previous has been queued, the first one will be skiped. The feature is available starting from JSF 2.2:
Bean.java
@ManagedBean
@ViewScoped
public class Bean {
public Date getCurrentDate(){
return new Date();
}
}
