binding problems - please help
I am not able to bind a richfaces control to a backing bean. When I do I always get

I have tried binding a datascroller as well as a scrollabledatatable, and always get the same response. I am pretty confident that my code is correct. Here is an exampel with the datascroller
xhtml
.
.<rich:datascroller
id="lnScroller"
align="left"
for="lnList"
maxPages="20"
pageIndexVar="pageIndex" pagesVar="pages"
binding="#{caseManagement.datascroller}">
<f:facet name="pages">
<h:outputText value="#{pageIndex} / #{pages}"></h:outputText>
</f:facet>
</rich:datascroller>
bakcinbg bean
private HtmlDatascroller datascroller;
.
.
public HtmlDatascroller getDatascroller() {
return datascroller;
}
public void setDatascroller(HtmlDatascroller datascroller) {
this.datascroller = datascroller;
}My only thought is that there is a problem with classloading - I am using Maven. Since I need richfaces-ui to compile the backing bean - since it references an org.richfaces.component.html.HtmlDatascroller, and we also need richfaces-ui in web-inf/lib - Where should my richfaces libraries go?
I have an EAR project structure, so I am assuming that I put richfaces-impl and richfaces-ui in web-inf/lib, and richfaces-ui and richfaces-api in my EAR /lib directory. Is this correct? does anyone have a maven EAR project structure pom file for when you want to use binding in a backing bean? An ythoughts on this would be helpfull as I can not bind ANYTHING
