Flex 4 with php error.

Question

Hi all, i'm connecting a flex application with database MySql, for that i'm using PHP as server side language. I followed a tutorial and created php class and tested. I'm getting the error at last step. This is what i did,
1) create a php class name.php
<?php
* This sample service contains functions that illustrate typical
* service operations. This code is for prototyping only.
*  Authenticate users before allowing them to call these methods.
class name {
  var $username = "root";
  var $password = "";
  var $server = "localhost";
  var $port = "3306";
  var $databasename = "test";
  var $tablename = "names";
  var $connection;
  public function __construct() {
    $this->connection = mysqli_connect(
                       $this->server, 
                       $this->username, 
                       $this->password,
                       $this->databasename,
                       $this->port
    $this->throwExceptionOnError($this->connection);
  public function getNames() {
     $stmt = mysqli_prepare($this->connection,
          "SELECT
              names.firstname,
              names.middlename,
              names.lastname
           FROM names");    
      $this->throwExceptionOnError();
      mysqli_stmt_execute($stmt);
      $this->throwExceptionOnError();
      $rows = array();
      mysqli_stmt_bind_result($stmt, $row->firstname, $row->middlename,
                    $row->lastname);
      while (mysqli_stmt_fetch($stmt)) {
          $rows[] = $row;
          $row = new stdClass();
          mysqli_stmt_bind_result($stmt, $row->firstname, $row->middlename,
                    $row->lastname);
      mysqli_stmt_free_result($stmt);
      mysqli_close($this->connection);
      return $rows;
   private function throwExceptionOnError($link = null) {
    if($link == null) {
      $link = $this->connection;
    if(mysqli_error($link)) {
      $msg = mysqli_errno($link) . ": " . mysqli_error($link);
      throw new Exception('MySQL Error - '. $msg);
2)   Through data wizard, connect php and linked php class, it showed the methods and went to final step.
3) Created a datagrid in flex, then dragged and droped getNames() to the datagid, then i configured return type. The datagrid then changed its fields to MySql table.
4) Here was the problem, when i ran the application, it showed a error in this line,
<fx:Script>
                    <![CDATA[
                              import mx.controls.Alert;
                              import mx.events.FlexEvent;
                              protected function dataGrid_creationCompleteHandler(event:FlexEvent):void
                                        getNamesResult.token = name.getNames();
                    ]]>
          </fx:Script>
Error -

Flex Problem
I'm new to flex, so wondering where exactly is the problem?
I did traced back few steps, like followed Control+click on getNames(), but it took me to actionscript file and everything seemed perfect. Since you guys have experience, hope you would throw some light on error. Thanks!
