How To Re-Use same Visual Web JSF page but Different Informmation?

Dear Sirs et Madames,
Am wanting to display a list of locations via a table with 3 columns, Location Id, Location Name, Location Type. Location name is a hyperlink and on clicking it, it is meant to take you to a table of child locations (all location found within the location you clicked on). The new child location table also displays same information i.e Location Id, Location Name, Location Type. I do not see the point of navigating to a whole new page to display child locations how can I re-use the same page to display the child locations as I used to display the parent locations? I have tried the following to achieve this but all I get is always the parent locations table being rendered. The page Bean is as follows:

package openhrs;

import com.sun.rave.web.ui.appbase.AbstractPageBean;
import javax.faces.FacesException;
import org.openhrs.businesslogic.location.LocationBusinessLogic;
import org.openhrs.location.vo.LocationVO;

public class ViewLocationList extends AbstractPageBean {
    // <editor-fold defaultstate="collapsed" desc="Managed Component Definition">
    
   
    private void _init() throws Exception {
    }
    
    // </editor-fold>
    private LocationVO[] locationArray;

public LocationVO[] getLocationArray() {
        return locationArray;
    }

public void setLocationArray(LocationVO[] locationArray) {
        this.locationArray = locationArray;
    }
    
    
    public ViewLocationList() {
    }
    
    @Override
    public void init() {
        
        locationArray = new LocationBusinessLogic().buildLocationTable
                (getSessionBean1().getParentId());

try {
            _init();
        } catch (Exception e) {
            log("OpenHRSTemplate Initialization Failure", e);
            throw e instanceof FacesException ? (FacesException) e: new FacesException(e);
        }
        
   }
    
        @Override
    public void preprocess() {
    }
    
        @Override
    public void prerender() {
    }
    
       @Override
    public void destroy() {
    }
    
    /**
     * <p>Return a reference to the scoped data bean.</p>
     *
     * @return reference to the scoped data bean
     */
    protected SessionBean1 getSessionBean1() {
        return (SessionBean1) getBean("SessionBean1");
    }
    
    /**
     * <p>Return a reference to the scoped data bean.</p>
     *
     * @return reference to the scoped data bean
     */
    protected RequestBean1 getRequestBean1() {
        return (RequestBean1) getBean("RequestBean1");
    }
    
    /**
     * <p>Return a reference to the scoped data bean.</p>
     *
     * @return reference to the scoped data bean
     */
    protected ApplicationBean1 getApplicationBean1() {
        return (ApplicationBean1) getBean("ApplicationBean1");
    }

public String hyperlink1_action() {
        getSessionBean1().setLocationParentId((Integer)getValue
                ("#{currentRow.value['locationId']}"));       
        return null;
    }
   
}

LocationBusinessLogic looks thus:

public class LocationBusinessLogic {

private LocationDao dao = new LocationDao();
    private List<LocationVO> locationList;

    }

        return dao.getLocationsAsVOs();
    }
    /* Get a list of top level locations as VO's */

public List<LocationVO> setLocationTypes(Integer parentId) {

List<LocationVO> locations = new LocationDAOConcrete().getLocationsAsVOs(0);
        Properties props = new Properties();

try {
            props.load(new FileInputStream("F:/svn/OpenHRS/OpenHRS/src/java/" +
                    "openhrs/locationType.properties"));

}
        catch (FileNotFoundException fnf) {
            fnf.printStackTrace();
        }
        catch (EOFException fnf) {
            fnf.printStackTrace();
        }
        catch (IOException ioe) {
            ioe.printStackTrace();
        }

for(LocationVO location: locations){
            //location.setLocationTypeName(props.getProperty(Integer.toString(location.getLocationTypeId())));
            Integer locationTypeId = location.getLocationTypeId();
            String locationTypeName = props.getProperty(Integer.toString(locationTypeId));
            location.setLocationTypeName(locationTypeName);
        }
        locationList = new ArrayList();
        locationList = locations;
        return locationList;
    }

public LocationVO[] buildLocationTable(Integer parentId) {
        setLocationTypes(parentId);

LocationVO[] locationArray = new LocationVO[locationList.size()];

return UtilityMethods.buildGenericTable(locationList, locationArray);

}
   
}

UtilityMethods looks thus:

As I say, the page re-renders but not with the desired effect as it always displays the same (Parent Locations) table rather than re-rendering with child locations when a paent Name (hyperlink) is clicked. Any help or suggestions would be greatly appreciated.

Thanks in advance
