input numer of pages in datascroller

[suckerd]

FYI

I managed the following using the latest richfaces 3.0.2_SNAPSHOT:

datascoller looking like << < x of 33 > >> instead of all the pager Links

code snipplet:

<rich:datascroller for="dataTable" id="scroller" binding="#{user.scroller}" boundaryControls="show" fastControls="show" stepControls="show">
<f:attribute name="pageIndexVar" value="pageIndexVar" />
<f:attribute name="pagesVar" value="pagesVar" />
<f:facet name="pages" id="pages">
<h:panelGroup>
<h:inputText id="pager" value="#{user.pageIndex}" size="2" >
<a4j:support event="onkeyup" reRender="dataTable,scroller" requestDelay="100" immediate="true"/>
</h:inputText>
<h:outputText id="maxPages" value="/ #{pagesVar}" />
</h:panelGroup>
</f:facet>
</rich:datascroller>

hope this helps anyone ;)

if you post your baking bean it will be great.

Thank you,

[grdzeli_kaci]

if you post your backing bean it will be great.

Thank you,

[suckerd]

and this would be the parts of the backingbean:

......
private UIDatascroller scroller;

public int getPageIndex() {
return this.scroller.getPageIndex();
}

public void setPageIndex(int index) {
int pageCount = this.scroller.getPageCount();
if (index > pageCount) {
index = pageCount;
} else if (index <= 0) {
index = 1;
}
this.scroller.setPage(index+"");
}

public UIDatascroller getScroller() {
return this.scroller;
}

public void setScroller(UIDatascroller scroller) {
this.scroller = scroller;
}
......etc.

hi suckerd,
i use richfaces 3.1.0 on my jboss seam project, i have done everything what you say but i got an exception :

Caused by: javax.el.ELException: /jguru/issue/content/admin/usrgrroles/projroleprowser.xhtml @111,183 binding="#{roleBean1.scroller}": java.lang.IllegalArgumentException: argument type mismatch

my example :
1. view

<scroller:datascroller for="permission" id="scroller" binding="#{roleBean1.scroller}" boundaryControls="show" fastControls="show" stepControls="show">
 <f:attribute name="pageIndexVar" value="pageIndexVar" />
 <f:attribute name="pagesVar" value="pagesVar" />
 <f:facet name="pages" id="pages">
 <h:panelGroup>
 <h:inputText id="pager" value="#{roleBean1.pageIndex}" size="2" >
 <a4j:support event="onkeyup" reRender="permission,scroller" requestDelay="100" immediate="true"/>
 </h:inputText>
 <h:outputText id="maxPages" value="/#{pagesVar}" />
 </h:panelGroup>
 </f:facet>
 </scroller:datascroller>

2. java backing bean

@Name("roleBean1")
public class TmpBean {

 private UIDatascroller scroller;

 public UIDatascroller getScroller() {
 return this.scroller;
 }

 public void setScroller(UIDatascroller scroller) {
 this.scroller = scroller;
 }

 public int getPageIndex() {
 return this.scroller.getPageIndex();
 }

 public void setPageIndex(int index) {
 int pageCount = this.scroller.getPageCount();
 if (index > pageCount) {
 index = pageCount;
 } else if (index <= 0) {
 index = 1;
 }
 }
}

did i something incorrect ? do you have this in seam project ??

Thanks In Advance.

It works fine xD.

I used that:

<rich:datascroller id="scroller" for="DataTable" maxPages="1" boundaryControls="show" fastControls="hidden" stepControls="show">
<f:attribute name="pageIndexVar" value="pageIndexVar" />
<f:attribute name="pagesVar" value="pagesVar" />
<f:facet name="previous">
<h:panelGroup>
<h:outputText value="Prev"/>
</h:panelGroup>
</f:facet>
<f:facet name="next">
<h:panelGroup>
<h:outputText value="Next"/>
</h:panelGroup>
</f:facet>
<f:facet name="pages">
<h:panelGroup>
<h:outputText id="pager" value="#{pageIndexVar}">
<a4j:support event="onkeyup" reRender="dataTable,scroller" requestDelay="100" immediate="true"/>
</h:outputText>
<h:outputText id="maxPages" value="/ #{pagesVar}" />
</h:panelGroup>
</f:facet>
</rich:datascroller>
