Alexander Smirnov commented on RF-3013:
---------------------------------------
I can't reproduce this problem. In the my sample, requests performed after event
only.
There is part of the my worked sample :
package org.ajax4jsf;
import java.util.ArrayList;
import java.util.Date;
import java.util.EventListener;
import java.util.EventObject;
import java.util.List;
import org.ajax4jsf.event.PushEventListener;
public class MessageBean implements Runnable {
private String result;
private boolean running = true;
private PushEventListener listener;
private List messages = new ArrayList(10);
private int counter = 0;
public MessageBean() {
// TODO Auto-generated constructor stub
}
/**
* @return the result
*/
public String getResult() {
return result;
}
/**
* @param result
* the result to set
*/
public void setResult(String result) {
this.result = result;
}
public void addListener(EventListener listener) {
synchronized (listener) {
if (this.listener != listener) {
this.listener = (PushEventListener) listener;
Thread th = new Thread(this);
th.start();
}
}
}
public void run() {
try {
while (isRunning()) {
Thread.sleep(10000);
Date current = new Date(System.currentTimeMillis());
if(messages.size()>=10){
messages.remove(0);
}
messages.add(messages.size(),String.valueOf(counter++)+" at
"+current.toString());
System.out.println("event occurs");
synchronized (listener) {
listener.onEvent(new EventObject(this));
}
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
/**
* @return the running
*/
public synchronized boolean isRunning() {
return running;
}
/**
* @param running
* the running to set
*/
public synchronized void setRunning(boolean running) {
this.running = running;
}
/**
* @return the messages
*/
public List getMessages() {
return messages;
}
/**
* @param messages the messages to set
*/
public void setMessages(List messages) {
this.messages = messages;
}
}

a4j:push ALWAYS (not only if event occurs) rerendering specified

------------------------------------------------------------------------------
Key: RF-3013
URL: http://jira.jboss.com/jira/browse/RF-3013
Project: RichFaces
Issue Type: Bug
Affects Versions: 3.2.0.SR1, 3.2.1
Environment: JDK 1.6
JBOSS 4.0.3 SP1
Facelets
JSF-RI
Reporter: Jens Behrens
Assigned To: Tsikhon Kuprevich
Priority: Critical
Fix For: 3.2.1
I tried the new classes from asmirnov, fixing the issue
http://jira.jboss.com/jira/browse/RF-2960
The eventProducer method is getting called now, but actually rerendering of specified
components is happening always and not only if an event occurs via onEvent method of the
listener...
The component has interval 3000, so every 3 seconds the msg component is rerendered
instead of checking if there actually is an event in queue.
