How to bind the rich:datascroller component

[thiagu.m]

Hai everyone
I need to bind the rich:datascroller component with my backing bean
I try that, but I can’t, I need some help

This is my xhtml code

<rich:datascroller binding="#{productsearch. dataScroller }" ajaxSingle="false" for="prodList" maxPages="10" >

This is my session bean code

@Name("productsearch")
public class ProductsAction implements ProductsLocal,Serializable
{
 Private org.richfaces.component.UIDatascroller dataScroller;

 public UIDatascroller getDataScroller() {
 return dataScroller;
 }


 public void setDataScroller(UIDatascroller dataScroller) {
 this.dataScroller = dataScroller;
 }
}

But I got this Exception

Caused by: javax.el.ELException: /ProductTableList.xhtml @568,153 binding="#{productsearch.dataScroller}": java.lang.IllegalArgumentException: argument type mismatch
 at com.sun.facelets.el.TagValueExpression.setValue(TagValueExpression.java:101)
