---------------------------------
There is delay in between repeated subscription after disabling and enabling push:
RF-12096
Incorrect behavior of two pushes on the page
--------------------------------------------
Key: RF-12095
URL: https://issues.jboss.org/browse/RF-12095
Project: RichFaces
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: component-push/poll
Affects Versions: 4.2.0.Final
Reporter: Lukáš Fryč
When you have 2 pushes on the page and one is conditionally rendered, rerendering it
causes unsubscribing of second push:

@ManagedBean
public class RichBean {
public Date getDate() {
return new Date();
}
public void push() throws MessageException {
TopicKey topicKey = new TopicKey("sampleAddress");
TopicsContext topicsContext = TopicsContext.lookup();
topicsContext.publish(topicKey, new Date().toString());
System.out.println("push event");
}
public void push2() throws MessageException {
TopicKey topicKey = new TopicKey("sampleAddress2");
TopicsContext topicsContext = TopicsContext.lookup();
topicsContext.publish(topicKey, new Date().toString());
System.out.println("push event 2");
}
}
{code}
Steps to reproduce:
1. open the page
2. you can see "subscribed" and "subscribed2" alert messages
3. both, Push! and Push 2! buttons reloads respective dates
4. click on checkbox and on the right of Push! button
EXPECTED: only Push! should stop to work
ACTUAL: both Push! and Push 2! stops to work
