rich:datascroller doesn't scroll

[veniero]

Hi everyone,

this is my first topic , and I hope to find nice persons to grow together.

this is my problem:

I'm working on a Spring webflow-jsf-richfaces project and I'm trying to use a rich:datascroller in a rich:dataTable, it is rendered, the pagination is created, but I can't navigate from page to page.
Simply the page doesn't change.
If I use Firebug console, and click on a page, I see that "Event.fire is not a function", referring to "<td class="rich-datascr-inact " onclick="Event.fire(this, 'rich:datascrollernscroll', {'page': '2'});">2</td>".

main jars are:
richfaces-ui 3.3.3
richfaces-api 3.3.3
richfaces-impl 3.3.3
spring-web-flow 2.3.0
spring 3.0.5
jsf-impl-1.2_12.jar
jsf-facelets-1.1.12.jar

can you help me?
thanks,
Veniero
