[richfaces-issues] [JBoss JIRA] (RF-13450) page attribute on dataScroller doesn't work with a request scope

[Brian Leathem (JIRA)]

    [ https://issues.jboss.org/browse/RF-13450?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12933675#comment-12933675 ] 

Brian Leathem commented on RF-13450:
------------------------------------

For the data scroller to work with a request scoped bean, the ajax request will have to be checked to make sure it is sending the current page with every request, and updating the backing bean value appropriately.

> Here the dataTable with a dataScroller:
> {code}
> 			<rich:dataScroller for="table" maxPages="5"
> 				page="#{currentPage.page}" />
> 			<rich:dataTable value="#{carsBean.allInventoryItems}" var="car"
> 				id="table" rows="10">
> 				<rich:column>
> 					<f:facet name="header">
> 						<h:outputText value="Vendor " />
> 					</f:facet>
> 					<h:outputText value="#{car.vendor}" />
> 				</rich:column>
>                                 ...
>                           </rich:dataTable>
> {code}
> Here the definition of the currentPage bean:
> {code}
>     <managed-bean>
>         <managed-bean-name>currentPage</managed-bean-name>
>         <managed-bean-class>prova.CurrentPage</managed-bean-class>
>         <managed-bean-scope>request</managed-bean-scope>
>     </managed-bean>
> {code}
> Here the currentPage bean:
> {code}
> package prova;
> public class CurrentPage {
> 	
> 	private int page = 1;
> 	public int getPage() {
> 		return page;
> 	}
> 	public void setPage(int page) {
> 		this.page = page;
> 	}
> }
> {code}
> the 'page' attribute in the dataScroller configuration doesn't work if set to 'request' scope. The buttons rewind and forward are blocked and it doesn't work. If I configure it with a 'session' scope that's ok
