Ok!

I made what are you tell me to do but I don't realy know how to implement this.

My java class extends BasePage already and implements PageRenderListener

I saw an example (VLIB) from tapestry 4 package but I didn't undersand how it works.

I made class MyEngine.java

package app.web;


import java.io.IOException;
import org.apache.tapestry.IRequestCycle;
import org.apache.tapestry.StaleSessionException;
import org.apache.tapestry.event.PageEvent;
import org.apache.tapestry.event.PageRenderListener;
import org.apache.tapestry.html.BasePage;
import org.apache.tapestry.request.ResponseOutputStream;
import org.apache.tapestry.form.*;
import org.apache.tapestry.engine.BaseEngine;
import org.apache.tapestry.form.IPropertySelectionModel;
import javax.servlet.ServletException;

public class MyEngine extends BaseEngine

{ private void handleStaleSessionException(StaleSessionException ex, IRequestCycle cycle, ResponseOutputStream output) throws IOException, ServletException

                 {
                 System.out.println("StaleSessionException!");

MeniuCautare search= (MeniuCautare) cycle.getPage("MeniuCautare");

                 cycle.activate(search);
                 renderResponse(cycle, output);
              }

}

How should I implement this class in my application ?

Thank you

I tried to override handleStaleSessionException in my Own Class that excends BasePage but dindn't work.

You need to extend BaseEngine, not BasePage.

this is overriding method:

private void handleStaleSessionException(StaleSessionException ex, IRequestCycle cycle, ResponseOutputStream output) throws IOException, ServletException

   {

   System.out.println("StaleSessionException!");
  SearchM search= (SearchM) cycle.getPage("SearchM");
   cycle.activate(search);

   }

Try:

private void handleStaleSessionException(StaleSessionException ex, IRequestCycle cycle, ResponseOutputStream output) throws IOException, ServletException

    {
    System.out.println("StaleSessionException!");
    SearchM search= (SearchM) cycle.getPage("SearchM");
    cycle.activate(search);
    renderResponse(cycle, output);
 }
