Calling AMF service with response from prior request

Hi all,

It's been a while since I last used SoapUI (3.6.1 Build dist-111-2010-10-18) and I'm pleased to see that AMF support has been added.

Here's my problem.

I have a TestStep that creates a new user by calling userService.createOrUpdate. I have made a jar of the relevant classes and dropped it into SOAPUI/bin/ext. With the following script it works fine and the user is created.

@Transactional
 @Secured("ROLE_ADMIN")
 public void createOrUpdate(User user) throws Exception
 {
  if (user.getCompany()== null) {
   user.setCompany(companyDAO.get(1));
  }
  
  userDAO.createOrUpdate(user);

  String password = user.getPassword();
  Object salt = saltSource.getSalt(user);
  
  user.setPassword(passwordEncoder.encodePassword(password,salt));
  userDAO.merge(user);
 }

import com.twoh.dto.User
import com.twoh.dto.Company

def u = new User()
def c = new Company()

// Set up the User.Company only the id is required
// when adding a user
c.id = 1

// Set up the new User mandatory fields
u.id = 0
u.username = "soapui"
u.password = "soapui"
u.company = c

// Update the parameters value
parameters['user'] = u

I then have a TestStep that calls userService.getByUsername which returns a response like the one below (good so far ...).

 @Transactional(readOnly=true)
 @Secured("ROLE_USER")
 public User getByUsername(String username) {
  return userDAO.findByUsername(username);
 }

      <namedType>com.twoh.dto.User</namedType>
    </default>
  </flex.messaging.io.amf.ASObject>
</flex.messaging.io.amf.ASObject>

My problem comes when I try to call the userService.deleteUser.

 @Transactional
 @Secured("ROLE_USER")
 public void deleteUser(User user) {
  userDAO.delete(user);
 }

I have tried setting the "user" property of this step to ${Retrieve user "soapui"#ResponseAsXML} and I have also tried adding the script

import flex.messaging.io.amf.client.AMFConnection;
import com.twoh.dto.User;

AMFConnection.registerAlias("com.twoh.dto.User","com.twoh.dto.User"); 

But I still get the error:

Any thoughts on what I am doing wrong ?
