Lukáš Fryč updated RF-11483:
----------------------------
Comment: was deleted
(was: This issue is much more critical, because the {{PushContext}} is not initialized
properly in time when needs to be used in order to initialize {{PushServlet}} properly.
{{PushContext}} is initialized in Showcase when {{TopicsContext#lookup()}} is called,
which is called by {{TopicsInitializer}} at JSF application startup.
So following {{NullPointerException}} is thrown because {{PushContextImpl#init(...)}}
wasn't called yet.

Elegant way for Push topic creating
-----------------------------------
Key: RF-11483
URL:
https://issues.jboss.org/browse/RF-11483
Project: RichFaces
Issue Type: Feature Request
Security Level: Public(Everyone can see)
Components: component-push/poll, core
Affects Versions: 4.1.0.Milestone1
Reporter: Lukáš Fryč
Assignee: Lukáš Fryč
Priority: Critical
Fix For: 4.3-Tracking
Currently, topics have to be initialized with similar class:
https://github.com/richfaces/showcase/blob/4.1.0.20110910-M2/src/main/jav...
I suggest to create topic on demand (lazily), when it is accessed first.
It needs following changes:
* {{PushRendererBase}} - will create Topic for @address attribute
* {{JMSTopicsContextImpl}} - will create topic when JMS message received
* {{PushObserverMethod}} - will create topic when @Push event for given topic observed
* ...
