identity manager - duplicate user role mapping created on new user creation

19. Aug 2008, 16:02 CET | Link adam tarshis

When creating a new userAccount object using identity manager in seam SVN latest copy, i am getting duplicate userAccount/userRole mappings created when i merge the userAccount object after setting the customer on the userAccount.

My example is basically the same as the seamspace MemberAcount/Member example, where userAccount is MemberAccount and Customer is Member.

Once i remove the merge line (commented out below), i get only a single userAccount/userRole mapping and everything works fine.

Here is the code:

	/**
	 * Create user account, log the user in, and display
	 */
	public void end() 
	{  
		new RunAsOperation() {
			public void execute() {
				identityManager.createUser(customer.getEmail(), password);
				identityManager.grantRole(customer.getEmail(), "user");
			}
		}.run();

		entityManager.persist(customer);
          
		userAccount.setCustomer(customer);
		//entityManager.merge(userAccount);

		// Login the user
		identity.setUsername(userAccount.getUserName());
		identity.setPassword(password);
		identity.login();
   }
