Quando tiro a tag <rich:datascroller> a pagina reenderiza normalmente,
já apliquei todas as sujestões postadas no seguinte link: http://www.guj.com.br/posts/list/65205.java
e nada funcionou!

View

<f:view>
        <a4j:form id="form1">
            <a4j:outputPanel>
                <rich:datascroller ajaxSingle="true" for="dataScroll1" maxPages="13" onclick="window.alert('clicou')" rendered="true"/>
                <rich:spacer height="30"/>
                <rich:dataTable columnClasses="column-index" id="dataScroll1" rendered="true" rowClasses="list-row3" rows="20" styleClass="list-table1"
                    title="Listagen de Empresas" value="#{teste2.dataModel1}" var="currentRow">
                    <h:column id="column1">
                        <h:outputText id="outputText1" value="#{currentRow.nomfilial}"/>
                        <f:facet name="header">
                            <h:outputText id="outputText2" value="Empresa"/>
                        </f:facet>
                    </h:column>
                </rich:dataTable>
            </a4j:outputPanel>
        </a4j:form>
    </f:view>

no backing bean tenho:

private ListDataModel dataModel1;
    public ListDataModel getDataModel1() {
        return dataModel1;
    }
    public void setDataModel1(ListDataModel dataModel1) {
        this.dataModel1 = dataModel1;
    }

OBS: dataModel1 está populado
OBS: estou utilizando o Rich Faces 3.0.0, todos os outros componentes do rich faces estão funcionando normalmente;

Gostaria de saber se alguem ja passou pelo mesmo problema, agradeço se alguem puder me ajudar a solucionar o problema.

desde-já obrigado a todos;
