<b>Use-case:</b> While a user is viewing a voting results page, values on the table are updating as people are voting. I will use the same base sample as the [a4j:repeat=>http://livedemo.exadel.com/richfaces-demo/richfaces/repeat.jsf] with <b>Runnable</b> interface implementation which is used in [a4j:push demo=>http://livedemo.exadel.com/richfaces-demo/richfaces/push.jsf] in order to simulate periodic votes being placed. This will show how to use server side events to trigger the update on client side instead of just use polling which performs full form. In real life the use-case could be much more complex - user could watch for huge tables updates . Another goal of the sample is to show how to encode and update the changed cells on the client.

Then we specify that this <b>ChoisesBean</b> class will implement <b>Runnable</b> and add the same <b>start</b>, <b>stop</b> and <b>run</b> methods as in [a4j:push demo=>http://livedemo.exadel.com/richfaces-demo/richfaces/push.jsf] in order to <b>simulate voting process</b>. Also we will define push event producer method in similar way. Next code should be added:
