    Description

      Hello, when I use the following BeanClass and xhtml page, Datatable is not populated with data, despite the method getAll() returns ResultSet that contains customer names.
      Code line System.out.println(crs.getString("Name")) iterates through the ResultSet and prints customer names from customer table before the ResultSet is being returned to h:dataTable component. This is what I get in Tomcat log:

      Start of Debug

      End of Debug

      This is the ManagedBean:

      package com.corejsf;

      import java.sql.Connection;
      import java.sql.ResultSet;
      import java.sql.SQLException;
      import java.sql.Statement;
      import javax.annotation.Resource;
      import javax.faces.bean.*;
      import javax.sql.DataSource;
      import javax.sql.rowset.CachedRowSet;

      @ManagedBean
      @RequestScoped

      public class CustomerBean {

      @Resource(name="jdbc/Sufa") private DataSource ds;

      public ResultSet getAll() throws SQLException {

      Connection conn = ds.getConnection();
      try {

      Statement stmt = conn.createStatement();
      ResultSet result = stmt.executeQuery("SELECT * FROM customers");
      CachedRowSet crs = new com.sun.rowset.CachedRowSetImpl();
      crs.populate(result);

      System.out.println("Start of Debug");

      while(crs.next())

      { System.out.println(crs.getString("Name")); }

      System.out.println("End of Debug");

      return crs;

      } finally

      { conn.close(); }

      }
      }

      This is xhtml page:

      <?xml version="1.0" encoding="UTF-8"?>
      <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
      <html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:h="http://java.sun.com/jsf/html"
      xmlns:ui="http://java.sun.com/jsf/facelets">
      <h:body>
      <h:form>

      <h:dataTable value="#

      {customerBean.all}

      " var="customer">
      <h:column>
      <f:facet name="header">#

      {msgs.nameHeader}

      </f:facet>
      #

      {customer.Name}

      </h:column>
      </h:dataTable>

      </h:form>
      </h:body>
      </html>

      It's important to mention that the same code works perfect when I change JSF implementation to mojarra-2.1.7.
      It's seems like a bug.

      Thanks a lot
