Hello Everybody, I'm trying to add dataScroller funcionality to a page in which I have a list of elements (datatable), so I modified and added all stuff related to the dataScroller, like in the myfaces examples at Irian (http://www.irian.at/myfaces/dataScroller.jsf), to my JSP.
The page with the list appears with the navigation
buttons (to go pages back or forward) The number of
pages and elements found appear ok, but when I click
on next page, for example, it navigates but all
buttons for page navigation disappear, and I cannot go
back to the last page listing, the only way is to
press Back button in Mozilla :-(.
My JSP looks like this:
<h:panelGroup id="body">
<t:dataTable id="packsList"
value="#{PackAdminBean.packsList}"
var="lstPacksVar"
border="0"
headerClass="tableHeader"
rowClasses="tableRow1,tableRow2"
preserveDataModel="false"
rows="5">
<h:column>
<f:facet name="header">
<f:verbatim>Package Name</f:verbatim>
</f:facet>
<h:outputText
value="#{lstPacksVar.nombre}"/>
</h:column>
<h:column>
<f:facet name="header">
<f:verbatim>Product</f:verbatim>
</f:facet>
<h:outputText value="Lawyer"/>
<f:verbatim><br></f:verbatim>
<h:outputText value="Accountant"/>
<f:verbatim><br></f:verbatim>
<h:outputText value="Info"/>
<f:verbatim><br></f:verbatim>
<h:outputText value="Document"/>
</h:column>
<h:column>
<f:facet name="header">
<f:verbatim>Quantity</f:verbatim>
</f:facet>
<h:outputText
value="#{lstPacksVar.lawyer}"/>
<f:verbatim><br></f:verbatim>
<h:outputText
value="#{lstPacksVar.accountant}"/>
<f:verbatim><br></f:verbatim>
<h:outputText
value="#{lstPacksVar.info}"/>
<f:verbatim><br></f:verbatim>
<h:outputText
value="#{lstPacksVar.docs}"/>
</h:column>
<h:column>
<f:facet name="header">
<f:verbatim>Value</f:verbatim>
</f:facet>
<h:outputText
value="#{lstPacksVar.price}"/>
</h:column>
<h:column>
<f:facet name="header">
<f:verbatim>Modify</f:verbatim>
</f:facet>
<h:commandLink
actionListener="#{PackAdminBean.selectPack}"
action="ModifyPack">
<h:graphicImage value="images/edit.gif"
alt="Edit Pack"
width="15%"
style="border:0">
</h:graphicImage>
<f:param name="paqueteID"
value="#{lstPacksVar.id}"/>
</h:commandLink>
</h:column>
</t:dataTable>
<h:panelGrid columns="1" >
<t:dataScroller id="scroll_1"
for="packsList"
fastStep="10"
pageCountVar="pageCount"
pageIndexVar="pageIndex"
styleClass="scroller"
paginator="true"
paginatorMaxPages="9"
paginatorTableClass="paginator"
paginatorActiveColumnStyle="font-weight:bold;"
actionListener="#{PackAdminBean.scrollerAction}"
>
<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>
<f:facet name="fastforward">
<t:graphicImage
url="images/arrow-ff.gif" border="1" />
</f:facet>
<f:facet name="fastrewind">
<t:graphicImage
url="images/arrow-fr.gif" border="1" />
</f:facet>
</t:dataScroller>
</h:panelGrid>
</h:panelGroup>
In my Bean (PackAdminBean), I have added the
method that manages the navigation process, like this:
public void scrollerAction(ActionEvent event)
{
ScrollerActionEvent scrollerEvent =
(ScrollerActionEvent)event;
FacesContext.getCurrentInstance().getExternalContext().
log("scrollerAction: facet: " +
scrollerEvent.getScrollerfacet() +
", pageindex: " +
scrollerEvent.getPageIndex());
}
I though it was because my Bean in the
faces-config.xml has "request" scope, so I changed it
to application, like in the examples, but its
behaviour is the same.
I went to Jboss console looking for more information
and I found that:
1. When the dataScroller (datatable) page is loaded
There's no output in jboss console.
2. If I click Next button in the first page I get in
console this:
02:06:07,106 INFO [[/mycontext]] scrollerAction:
facet: next, pageindex: -1
so, in the navigator appears the next page, but the
buttons are not displayed.
3. I ended my session in the application and login
again and click on Fast Forward button, then in
console appears:
02:09:31,798 INFO [[/mycontext]] scrollerAction:
facet: fastf, pageindex: -1
it does the FastForward, but navigation buttons
disappear
4. If I click on First page being on it I get:
02:12:25,213 INFO [[/sajur]] scrollerAction: facet:
first, pageindex: -1
I see that pageindex is always -1, is this normal?
What could the problem be?
Thanks a lot,
Johnny
