I use <t:dataScroller>(MyFaces 1.1.3, tomahawk-1.1.2) like this:
<h:form id="videoListForm">
<t:dataTable id="videos" value="#{VideoListBean.videoList}" var="video" rows="1">
<h:column>
<f:facet name="header">
<h:outputText value="name"></h:outputText>
</f:facet>
<h:outputLink value="#{bundle.videoManagementUrl}">
<h:outputText value="#{video.chineseName}"></h:outputText>
<f:param name="videoId" value="#{
video.id}" />
</h:outputLink>
</h:column>
</t:dataTable>
<h:panelGrid columns="1">
<t:dataScroller id="scroll_1" for="" fastStep="1" pageCountVar="pageCount" pageIndexVar="pageIndex" paginator="true" paginatorMaxPages="9" paginatorActiveColumnStyle="font-weight:bold;" immediate="true"
actionListener="#{VideoListBean.scrollerAction}">
<f:facet name="first">
<t:graphicImage url=""
first.gif" border="1" />
</f:facet>
<f:facet name="last">
<t:graphicImage url=""
last.gif" border="1" />
</f:facet>
<f:facet name="previous">
<t:graphicImage url=""
previous.gif" border="1" />
</f:facet>
<f:facet name="next">
<t:graphicImage url=""
next.gif" border="1" />
</f:facet>
<f:facet name="fastforward">
<t:graphicImage url=""
ff.gif" border="1" />
</f:facet>
<f:facet name="fastrewind">
<t:graphicImage url=""
fr.gif" border="1" />
</f:facet>
</t:dataScroller>
<t:dataScroller id="scroll_2" for="" rowsCountVar="rowsCount" displayedRowsCountVar="displayedRowsCountVar" firstRowIndexVar="firstRowIndex" lastRowIndexVar="lastRowIndex" pageCountVar="pageCount" immediate="true" pageIndexVar="pageIndex">
<h:outputFormat value="#{bundle.videoScrollerPages}">
<f:param value="#{rowsCount}" />
<f:param value="#{displayedRowsCountVar}" />
<f:param value="#{firstRowIndex}" />
<f:param value="#{lastRowIndex}" />
<f:param value="#{pageIndex}" />
<f:param value="#{pageCount}" />
</h:outputFormat>
</t:dataScroller>
</h:panelGrid>
</h:form>
But when I click "2", "next" or "fastforward", an error is reported:
