Primefaces datatable only show last item

[Enrique Villamizar]

Hi to everyone:

I´m taking my first steps on PrimeFaces. I'm running a dataTable but the page only shows the last item of a list and I have no idea what I'm missing.

NetBeans 6.9
JSF 2.0
Apache Tomcat 6.0
JDK 1.6
primefaces-2.2.M1.jar

My *.xhtml page:

     <p:dataTable var="car" value="#{tableBean.carsSmall}">
                <f:facet name="header">
                    List of Cars
                </f:facet>
                <p:column>
                    <f:facet name="header">
                        Model
                    </f:facet>
                    <h:outputText value="#{car.modelo}" />
                    <f:facet name="footer">
                        Pie
                    </f:facet>
                </p:column>
                <p:column headerText="Manufacturer">
                    <h:outputText value="#{car.fabricante}" />
                </p:column>
                <p:column headerText="Color">
                    <h:outputText value="#{car.color}" />
                </p:column>
                <p:column headerText="Year" footerText="1960-2010">
                    <h:outputText value="#{car.anio}" />
                </p:column>
                <f:facet name="footer">
                    In total there are #{fn:length(tableBean.carsSmall)} cars.
                </f:facet>
            </p:dataTable> 

My Bean:

  @ManagedBean
@RequestScoped
public class TableBean implements Serializable {

    private List<Car> carsSmall;

  public TableBean() {  
       carsSmall = new ArrayList<Car>();
       Car car = new Car();
       for(int i = 0; i < 10; i++) {
           car.setAnio(2000 + i);
           car.setColor("Rojo " + i);
           car.setFabricante("Fabricante " + i);
           car.setModelo(i);
           carsSmall.add(car);
       }
  }

    public List<Car> getCarsSmall() {
        return carsSmall;
    }

    public void setCarsSmall(List<Car> carsSmall) {
        this.carsSmall = carsSmall;
    }

}  

The first problem is the folloing line:

  <f:facet name="footer">
                    In total there are #{fn:length(tableBean.carsSmall)} cars.
                </f:facet>  

Throws an error: javax.el.ELException: "fn:length" Not Found

When I delete the

 #{fn:length(tableBean.carsSmall)} 

the page is showed but it prints only the last item of the car list.

You car list contains only one element as you are using the same Car object. Instantiate Car object in for loop instead. And for number of your cars, use #{tableBean.carsSmall.length}.
