Hi Geeta,

Can you explain what the rowId signifies in the data table when using the paging component?

I'm still getting errors (see below, but I think it's still pretty basic). I added the basic.css to the JSP directory, but that didn't help.

                   <t:dataTable
                     id = "Data"
                     value="#{TD.txs}"
                     rows="10"
                     styleClass="orders"
                     headerClass="ordersHeader"
                     rowClasses="evenRow,oddRow"
                     width="100%"
                     var="tx"
                     rowId="#(tx.type}"
                     sortColumn="#{TD.sortColumn}"
                     sortAscending="#{TD.ascending}"
                     preserveDataModel="true" preserveSort="true">

And, my paging header:

<t:dataScroller
                          id="scroll_1"
                          for=""
                          fastStep="10"
                          pageCountVar="pageCount"
                          pageIndexVar="pageIndex"
                          styleClass="scroller"
                          paginator="true"
                          paginatorMaxPages="9"
                          paginatorTableClass="paginator"
                          paginatorActiveColumnStyle="font-weight:bold;">

                            <f:actionListener type="DataScrollerActionListener" />
                            <f:facet name="first">
                                <t:graphicImage url="" border="1" />
                            </f:facet>
                            <f:facet name="last">
                                <t:graphicImage url="" border="1" />
                            </f:facet>
                            <f:facet name="previous">
                                <t:graphicImage url="" border="1" />
                            </f:facet>
                            <f:facet name="next">
                                <t:graphicImage url="" border="1" />
                            </f:facet>
                            <f:facet name="fastforward">
                                <t:graphicImage url="" border="1" />
                            </f:facet>
                            <f:facet name="fastrewind">
                                <t:graphicImage url="" border="1" />
                            </f:facet>
                        </t:dataScroller>
                    </h:panelGrid>

Hi Mike,

Here's a barebones paging code (I removed all style for simplicity) which works for me:

<h:form id="contactscrollerpagerform">
<t:saveState id="savesearchstate" value="#{search}" />
<h:panelGrid styleClass="scrollerTableNoBorder"
rendered="#{search.results}">
<h:column>
<h:panelGrid id="contactInfoPanelGrid">

<f:facet name="header">
<h:outputText value="Demographic search results" />
</f:facet>
<t:dataTable id="contactsearchdata"
var="contact" value="#{search.matchingContacts}" rows="7"
rowId="#{contact.id}" sortColumn="#{search.sort}"
sortAscending="#{search.ascending}" preserveSort="true">

<h:column>
<f:facet name="header">
<t:commandSortHeader columnName="lastname" arrow="true"
immediate="false">
<h:outputText value="Last Name" />
</t:commandSortHeader>
</f:facet>
<h:outputText value="#{contact.lastName}" />
</h:column>

</t:dataTable>
</h:panelGrid>
<h:panelGrid>
<t:dataScroller id="scroll_1" for="contactsearchdata" fastStep="10"
pageCountVar="pageCount" pageIndexVar="pageIndex"
paginator="true" paginatorMaxPages="3"
paginatorTableClass="paginator"
paginatorActiveColumnStyle="font-weight:bold;">

<f:facet name="first">
<t:graphicImage url="images/arrow-first.gif" border="1" />
</f:facet>
<f:facet name="last">
<t:graphicImage url="images/arrow-last.gif" border="1" />
</f:facet>
<f:facet name="previous">
<t:graphicImage url="images/arrow-previous.gif" border="1" />
</f:facet>
<f:facet name="next">
<t:graphicImage url="images/arrow-next.gif" border="1" />
</f:facet>
</t:dataScroller>
</h:panelGrid>
</h:column>
</h:panelGrid>
</h:form>

You are right about the "for" of the datascroller needing to match the "id" of the datatable. Also note I didn't have have any actionListeners at all. Plus, the style stuff is in basic.css (at least it was in the version i downloaded a little while back. So as long as you import that style sheet at the top of your jsp, the style will be picked up.

Hope this helps,
Geeta
