How to preserve row state in richfaces dataTable?

[bjcldqpulj]

Hi,
I want to preserve the dataModel / table rows when I scroll through the datatable, but I want to refresh / reload the data when I navigate to this page from some other page.

I tried <a4j:keepAlive beanName="logLoadController" ajaxOnly="true"/>
, but it does not preserve the bean when i scroll through the dataScroller.

I am using richfaces 3.1.4 GA

<rich:dataTable id="logTable" rows="10"
 value="#{logLoadController.allLogs}" var="row" rowKeyVar="index"
 binding="#{logLoadController.htmlDataTable}">
 <rich:column>
 <h:selectBooleanCheckbox value="#{row.selected}">
 </h:selectBooleanCheckbox>
 </rich:column>
 ... other columns
</rich:dataTable>
<rich:datascroller id="logDatascroller" align="left"
 for="logTable" ajaxSingle="false"/>

faces-config.xml
 <managed-bean>
 <managed-bean-name>logLoadController</managed-bean-name>
 <managed-bean-class>
 LogLoadController
 </managed-bean-class>
 <managed-bean-scope>request</managed-bean-scope>
 <managed-property>
 <property-name>logLoadDao</property-name>
 <value>#{logLoadDao}</value>
 </managed-property>

At first using keepAlived bean in binding - even worse that use just session scoped bean and could cause any unpredictable glitches. binding property should be request scoped.
