Strange behavior: action method not called when button submitted

Question

Hello,
My JSF app is diplaying a strange behavior: when the submit button is pressed the action method of my managed bean is not called.
Here is my managed bean:
package arcoiris;
import java.util.ArrayList;
import java.util.List;
import javax.faces.model.SelectItem;
public class SearchManagedBean {
    //Collected from search form
    private String keyword;
    private String country;

    private int rating;
    private boolean websiteExists;
    //Used to populate form
    private List<SelectItem> availableCountries;
    private List<SelectItem> availablePostcodes;
    private List<SelectItem> availableRatings;
    //Retrieved from ejb tier
    private List<EstablishmentLocal> retrievedEstablishments;
    //Service locator
    private arcoiris.ServiceLocator serviceLocator;
    //Constructor
    public SearchManagedBean() {
        System.out.println("within constructor SearchManagedBean");
        System.out.println("rating "+this.rating);

Can anyone help please?
Thanks in advance,
