a4j:poll x slow action of a4j:commandButton

[edilmar]

Hi,

I use RichFaces3.3.3 + JSF2.0.

I have an a4j:commandButton with an action that needs to process many things.

I would like to use a4j:poll + h:outputText, to show a message for the actual process running, for better user interface.

Problem: when user clicks the button, the action runs, but reRender to activate the a4j:poll only occurs after action is finished.

Then, no message appears during processing.

I look at all livedemos from a4j:poll and a4j:push, but the action for commandButton in these demos is fast.

I made a bean for a4j:poll livedemo "Server date", based on http://livedemo.exadel.com/richfaces-demo/richfaces/poll.jsf?c=poll&tab=usage

First, I created a fast bean method and outputText worked fine, displaying the server date.

Then, I put a Thread.sleep(10000) to simulate a slow bean method. The same problem occured, not displaying anything.

I would like something like this:

if "user cliks button" then

  "first activate the a4j:poll"

  "after run the slow action"

endif

Is there some way to do this?

Thanks for any help.

Why you are not using rich:progressBar component?

Because it is not to show a % processing value. I need to show complete messages for the user.

And progressbar would have the same problem, that is to start it in a reRender of button.
