Oh.. At firts try to use latest versions of the RF and A4J, because of many issues was solved into. And check you JSF version it musn't be earlier than 1.1.02.

Hello!

Try wrapping dataScroller & dataTable into a4j:outputPanel.

I'm also running into problems with the dataScroller.

I just upgraded an old demo app of mine to use the latest libraries, and now the dataScroller doesn't reRrender the relevant bits on the page anymore.

I tried wrapping the table and scroller in a a4j:outputPanel, didn't work.
Tried with both h:form and a4j:form, no change.

The server side bits seems to get set, because when doing a refresh of the page it gets rendered properly.

Libs:
myfaces and tomahawk 1.1.5
ajax4jsf and richfaces snapshots are the latest
facelets 1.1.12

try to add ajaxRendered="true" to <a4j:outputPanel >
this example works well on my jboss 4.2.0 GA and richfaces 3.0.1

<a4j:form ajaxSubmit="true" >
<a4j:outputPanel ajaxRendered="true">
 <rich:datascroller id="carList_scroller" for="carList" maxPages="20" />
 <rich:spacer height="30" />
 <rich:dataTable width="483" id="carList" rows="10" columnClasses="col"
 value="#{dataTableScrollerBean.allCars}" var="category">
 <f:facet name="header">
 <rich:columnGroup>
 <h:column>
 <h:outputText styleClass="headerText" value="Make" />
 </h:column>
 <h:column>
 <h:outputText styleClass="headerText" value="Model" />
 </h:column>
 <h:column>
 <h:outputText styleClass="headerText" value="Price" />
 </h:column>
 <h:column>
 <h:outputText styleClass="headerText" value="Mileage" />
 </h:column>
 </rich:columnGroup>
 </f:facet>

 <h:column>
 <h:outputText value="#{category.make}" />
 </h:column>
 <h:column>
 <h:outputText value="#{category.model}" />
 </h:column>
 <h:column>
 <h:outputText value="#{category.price}" />
 </h:column>
 <h:column>
 <h:outputText value="#{category.mileage}" />
 </h:column>



 </rich:dataTable>

 </a4j:outputPanel>
</a4j:form>

Hi,

If I am using DataModel for datatable its giving aception
My extendedDataModel.jsp code is here

<f:view>
 <h:outputText value="Dinesh #{AuctionDataModel}"/>
 <h:form>
 <a4j:outputPanel ajaxRendered="true">
 <rich:datascroller for="auction" maxPages="5" />
 <rich:spacer height="30" />
 <rich:dataTable id="auction" value="#{AuctionDataModel}"
 columnClasses="col1,col2,col3,col4," var="item" rows="10"
 width="100%">
 <rich:column>
 <f:facet name="header">
 <h:outputText value="Description" />
 </f:facet>
 <h:outputText value="#{item.description}" />
 </rich:column>
 <rich:column>
 <f:facet name="header">
 <h:outputText value="Highest Bid" />
 </f:facet>
 <h:outputText id="highestBid" value="#{item.highestBid}">
 <f:convertNumber pattern="$#,##0.00" />
 </h:outputText>
 </rich:column>
 <rich:column>
 <f:facet name="header">
 <h:outputText value="Your Bid" />
 </f:facet>

 <rich:message for="bid" />
 <br />
 <h:inputText id="bid" value="#{item.bid}">
 <f:convertNumber />
 <f:validateLongRange minimum="0" maximum="1000000" />
 </h:inputText>
 <a4j:commandLink id="bid_link" actionListener="#{item.placeBid}"
 value="Place a bid!" reRender="bid,amount,highestBid" />

 </rich:column>
 <rich:column>
 <f:facet name="header">
 <h:outputText value="Amount" />
 </f:facet>
 <h:outputText id="amount" value="#{item.amount}">
 <f:convertNumber pattern="$#,##0.00" />
 </h:outputText>
 </rich:column>
 </rich:dataTable>
 </a4j:outputPanel>
 </h:form>
