PHP5 + soap extension + WSDL Mode

[dex]

Hi,

I'm trying use a webservice with PHP5 soap extension in WSDL mode.
I generated the php classes using wsdl2php.
The problem is that 'auth' member of loginRequest (witch is a complex
type) dosen't get serialized.
The 'version' member witch is decimal is being serialized and sent to
the server.
I am doing something wrong ?
full source code, including generated php classes at
http://www.rdanet.com/groupwise.zip
------------------------------------------------------------------>source

code:
<?
require_once('./gwservice/GroupwiseService.php');
$classmap = array(
'Authentication' => 'Authentication',
'PlainText' => 'PlainText',
'loginRequest' => 'loginRequest',
);
$gwservice = new GroupWiseService
(
"./wsdl/groupwise.wsdl",
array
(
"location" => "http://10.100.30.66:7191/soap",
"classmap" => $classmap,
"trace" => true,
"exceptions" => true
)
);
$pt = new PlainText();
$pt->username ="user";
$pt->password ="secret";
$lr = new loginRequest();
$lr->auth = $pt;
$lr->version =1;
print_r($lr);
print_r($gwservice->loginRequest($lr));
print_r($gwservice->__getLastRequest());
?>
------------------------------------------------------------------>response**:

php object:
loginRequest Object
(
[auth] => PlainText Object
(
[username] => user
[password] => secret
)
[language] =>
[version] => 1
[application] =>
)
