@WebParam header doesn't work

[dmarczydlo]

    /**
     * @WebMethod
     * @WebParam(param="string $token", header=true)
     * @WebParam(param="object $user { string $name int $age }")
     * @WebResult(param="object $userContext { string $token int $id object $userInfo { string $name int $age } }")
     */
    public function getUserContext($token, $user)
    {
        return $user;
    }

The code above doesn't work.
My Soap client return Too few arguments to function getUserContext(), 1 passed and exactly 2 expected

It looks like the $token variable is not handle.

@piotrooo do you know what can be a reason? I based on your test files
