rich:datascroller filter problems

[tryan702]

I'm using NetBeans6.1, RichFaces3.2.2, JSF1.2 and JDK1,6. I am having problems when using the datascroller for a datatable to allow multiple pages. When i use the filter it will limit the records in the datatable and the datascroller will only show the pages necessary to fit those records matching the filter but when i remove that filter the datascroller is not rerendering to show all the pages again. Any ideas? Here is the jsp page:

<rich:dataTable binding="#{Results.hdtResults}" id="hdtResults" var="currentRow" rows="#{Results.rowsPerPage}" />
<rich:datascroller for="hdtResults" binding="#{Results.hds}" renderIfSinglePage="false" pagesVar="#{Results.numPages}"/>

datascroller should be reRendered also with dataTable when you changing filter in order to be updated according to the dataTable current model

I was able to resolve this by putting the datatable and datascroller inside a rich:panel then having the datascroller reRender the panel. I couldn't figure out how to reRender the datascroller or datatable by changing the filter. How could you do that, the filter is part of the rich:column added to the datatable. Any ideas?

Use like this:
<rich:dataTable binding="#{Results.hdtResults}" id="hdtResults" var="currentRow" rows="#{Results.rowsPerPage}" reRender="datascroller"/>
<rich:datascroller id="datascroller" for="hdtResults" binding="#{Results.hds}" renderIfSinglePage="false" pagesVar="#{Results.numPages}"/>

Thank you for your reply. I have tried setting the reRender on the datatable to reRender the datascroller but that didn't work.

When the a4j:region looks like below the datascroller works properly:

<jsp:root version="2.1" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:jsp="http://java.sun.com/JSP/Page" xmlns:webuijsf="http://www.sun.com/webui/webuijsf"
xmlns:a4j="http://richfaces.org/a4j" xmlns:rich="http://richfaces.org/rich">
<jsp:directive.page contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"/>
<f:view>
<webuijsf:page id="ResultsPage" >
<webuijsf:html id="htmlResults" binding="#{Results.html1}">
<webuijsf:head id="head1" binding="#{Results.head1}">
<webuijsf:link id="link1" url="/resources/stylesheet.css"/>
</webuijsf:head>
<webuijsf:body id="body1">
<webuijsf:form id="form1" styleClass="lightGreyMaintd">
<a4j:region>
<h:outputText id="theDisplay" value="#{Results.xsltString}" escape="false" />
<rich:panel id="Results">
<rich:dataTable binding="#{Results.hdtQueryResults}" id="hdtResults" var="currentRow" reRender="hds"/>
<rich:datascroller id="hds" for="hdtResults" binding="#{Results.hds}" renderIfSinglePage="false" reRender="Results" pagesVar="#{Results.numPages}"/>
</rich:panel>
</a4j:region>
</webuijsf:form>
</webuijsf:body>
</webuijsf:html>
</webuijsf:page>
</f:view>
</jsp:root>

It does not work when i change a4j:region to this:
<a4j:region>
<h:outputText id="theDisplay" value="#{Results.xsltString}" escape="false" />
<rich:dataTable binding="#{Results.hdtQueryResults}" id="hdtResults" var="currentRow" reRender="hds"/>
<rich:datascroller id="hds" for="hdtResults" binding="#{Results.hds}" renderIfSinglePage="false" pagesVar="#{Results.numPages}"/>
</a4j:region>
