Problems with rich:datascroller

[m.schuetz]

Hi,
i just tried out the rich:datascroller example from RichFaces LiveDemo, but i doesn't work correctly. The datascroller is available, but without displaying page numbers and therefore quite useless.

Here's the code:

<h:form>

 <rich:datascroller for="companyList" maxPages="20" />

 <rich:spacer height="10" />

 <rich:dataTable id="companyList" value="#{assignedCompanies}"
 var="aCompany"
 onRowMouseOver="this.style.backgroundColor='#{a4jSkin.headerBackgroundColor}'"
 onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'"
 rendered="#{assignedCompanies.rowCount != 0}">

 <f:facet name="header">
 <rich:columnGroup>
 <h:column>
 <h:outputText value="Unternehmen" />
 </h:column>
 <h:column>
 <h:outputText value="ILN" />
 </h:column>
 <h:column>
 <h:outputText value="Bereich" />
 </h:column>
 </rich:columnGroup>
 </f:facet>

 <h:column>
 <s:link value="#{aCompany.displayName}"
 action="#{company.openCompany(aCompany)}" />
 </h:column>
 <h:column>
 <h:outputText value="#{aCompany.globalLocationNumber}" />
 <h:outputText value="nicht vorhanden"
 rendered="#{aCompany.globalLocationNumber == null}" />
 </h:column>
 <h:column>
 <h:outputText value="#{aCompany.systemScope}"
 converter="SystemScopeDisplayConverter" />
 </h:column>
 </rich:dataTable>
 <br />
 <s:link value="Neues Unternehmen anlegen"
 view="/user/createCompany.jsf" />
 </h:form>

Thank you
Michael

Michael,

what JSF version are you using? There is a limitation for the dataScroller component in JSF 1.1: it should go after the component it points to, inside it; or both components should reside in any container component that's rendersChildren method returns true. That is in order for the data component to be created before dataScroller component has been rendered.

I'm using JSF RI 1.2.
Could someone post a code snippet from a working version. That would be great.
Thanks

The main RichFaces example uses JSF 1.2 :

Michael,
there were some issues concerning SQL resultset data models in 3.0.0 release; they're now fixed in trunk. Can you please try to use another dataModel in your application, for example the one that is based on List?

[d.bulahov]

Michael, put in rich:dataTable attribute "rows" with quantity of rows on page and the page numbers will be displaying. Without this attribute all rows will be displaying

[m.schuetz]

That's it! Thanks for helping me! Everything works fine now.

But IMO the rich:datascroller maxPages attribute is quite useless now, while the page amount automatically depends on table row count.

[d.bulahov]

MaxPages is necessary for pages quantity limit in datascroler. I think there will be an opportunity first of maxPages, second of maxPages and so on.
