      Hi,

       

      I am stucked with datatable. I am using this on jsp page:

       

      <h:dataTable value="#{AList.myArr}" var="capt"  border="1" 
                headerClass="header"   rowClasses="row1,row2">
                    <h:column >
                        <f:facet name="header" > <f:verbatim>State</f:verbatim> </f:facet>
                        <h:outputText value="#{capt}" />
                    </h:column>
</h:dataTable>

       

      i am using arraylist to store some data in a bean Alist:

       

      package demo;

import java.util.*;
import java.io.*; 


public class Alist {
          ArrayList<String> myArr = new ArrayList<String>(10);
          public Alist() 
          { 
    myArr.add("Italian Riviera");
    myArr.add("Jersey Shore");
    myArr.add("Puerto Rico");
    myArr.add("Los Cabos Corridor");
    myArr.add("Lubmin");
    myArr.add("Coney Island");
    myArr.add("Karlovy Vary");
    myArr.add("Bourbon-l'Archambault");
    myArr.add("Walt Disney World Resort");
    myArr.add("Barbados");
          }
          public ArrayList<String> getMyArr() {
                    return myArr;
          }
          public void setMyArr(ArrayList<String> myArr) {
                    this.myArr = myArr;
          }
}

       

      I am using Richfaces 4 Final in JBoss Dev Studio 4 GA using JBoss 6 server.

      The display page only displays the header and no data from the arraylist. Kindly help me...

          Hi Jayesh,

          have you defined your Class as Managed Bean? (JSF 1.x: faces-config.xml, JSF 2.0: @ManagedBean, @SessionScoped (for example) annotations in your Class).

           

          Best regards,

          Mark

            Hi,

             

            A very strange thing happenned. Yesterday the whole day i was tried to run it by changing codes, face-config, republishing etc but it didn't run. Today the first thing i did was open up the app and run it and there it was, running very well, displaying all the data. earlier whne i changed the static content, it did reflect in the web page, so publishing was working.

             

            Anyhow now i have to implement sorting but the moment i click in the sort header, nothing happens except that the URL is appended by a # sign. Here is the sorting class which i have defined:

            package demo;
import org.richfaces.component.SortOrder;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
import javax.faces.bean.SessionScoped;

@ManagedBean
@ViewScoped
@SessionScoped
public class sorting {
          private SortOrder capSort = SortOrder.unsorted;

          public void sortByCaps(){
                    if (capSort.equals(SortOrder.ascending)) {
            setCapSort(SortOrder.descending);
        } else {
            setCapSort(SortOrder.ascending);
        }
          }

          public SortOrder getCapSort() {
                    return capSort;
          }

          public void setCapSort(SortOrder capSort) {
                    this.capSort = capSort;
          }
}

            And the modified xhtml page is as below:

            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:a4j="http://richfaces.org/a4j"
    xmlns:rich="http://richfaces.org/rich">
    <h:form>
        <rich:dataTable value="#{AList.myArr}" var="capt" id="table">
            <rich:column sortBy="#{capt}" id="name" sortOrder="#{Sort.capSort}">
                <f:facet name="header">
                    <a4j:commandLink value="Sort by Name" render="table"
                        action="#{Sort.sortByCaps}" />
                </f:facet>
                <h:outputText value="#{capt}" />
            </rich:column>
        </rich:dataTable>
    </h:form>
</ui:composition>

            Kindly help me with this...

             

            Edit Note: In IE, I am getting a warning error on bottom-left of the browser which on clicking displays 'RichFaces' is undefined. Its a warning error though.
