Complex Types problem

Hi!

I'm trying to do a simple WS call with a parameter that should be built 
as ComplexType. I receive a "Cannot use object of type stdClass as 
array" error, I have try several things and the code is not working out. 
Here is my code:

WSDL
=====

<xsd:complexType name="SubscriberDataType">
  <xsd:all>
    <xsd:element name="age" type="xsd:integer"/>
    <xsd:element name="email" type="xsd:string"/>
    <xsd:element name="name" type="xsd:string"/>
  </xsd:all>
</xsd:complexType>
[...]

<message name="CreateSubscriber">
  <part name="subscriber" type="typens:SubscriberDataType"/>
</message>

<message name="CreateSubscriberResponse">
  <part name="CreateSubscriberReturn" type="xsd:integer"/>
</message>


PHP CLIENT
==========
<?php

define( 'WS_WSDL',  'http://hannibal/poc/PHP5_SOAP/wsdl/subscribers.wsdl' );

$client = new SoapClient( WS_WSDL );

$subscriber = array( 'age'   => (Integer) 27
                   , 'email' => (String) '[email protected]'
                   , 'name'  => (String) 'Dani'
                   );
                  
try
{
  $result = $client->CreateSubscriber( $subscriber );
  echo $result;
}
catch( SoapFault $exception )
{
  echo $exception->faultstring;
}

?>


PHP SERVER
==========
<?php

define( 'WS_WSDL',  
'http://localhost/poc/PHP5_SOAP/wsdl/subscribers.wsdl' );

function CreateSubscriber( $subscriber )
{
  $name  = $subscriber['name'];
  $email = $subscriber['email'];
  $age   = $subscriber['age'];
 
  return 200;
}//function CreateSubscriber( $name )


/******************/
class SubscriberDataType
{
  public $age; 
  public $email;
  public $name;
}//class SubscriberDataType


/*----------------MAIN-----------------*/

$server = new SoapServer( WS_WSDL );
$server->addFunction( 'CreateSubscriber' );
$server->handle( $GLOBALS['HTTP_RAW_POST_DATA'] );
die;

?>


Thank you in advance!
