a4j:push action on receive event

[svande]

Hello,

I have succesfully implemented a4j:push functionality.
I add a listener to the event producer like this:

eventProducer="#{contractsPollController.addListener}"

Events are indeed fired by the contractsPollController.

My question:
Can I read the event received by a4j:push?
Or otherwise:
Can I execute an action before rerender is done?

The reason is that my list is cached on the server and I want to empty the cache first before rerendering the list.

Any hints?

as you could see push has action and actionListener attributes. so you could define the methods you need to be executed on event.

Thanks!

I have another question on a4j:push:

Is there any way to know on the server how long the client has stopped polling for pushes?
I would like to stop some quartz scheduled process in that case...

I thought about it:
What does push do? Check the queue. Can we see when a queue was last checked? No.
