I have the following setup:

- LoginManager with 3 UserSources, one of them named CustomerUserSource.

- A Customers specialist, using a Customer ZClass for storage. 
Customer has a 'login' propertysheet with property 'password', and a 
getCustomerByName method returning a customer object.

- CustomerUserSource 'load by accessing attribute' is set to 'id'.

- A SkinScript in CustomerUserSource:

     WITH Customers.getCustomerByName(Customers, self.id) COMPUTE
     password=password, original_object=RESULT

The following PythonMethod:

     return obj.password

returns the correct password for customer 'jane', but this one:

     return obj.password

returns this:



Troubleshooting Suggestions

           This resource may be trying to reference a nonexistent object or
           variable password.
           The URL may be incorrect.
           The parameters passed to this resource may be incorrect.

     If the error persists please contact the site maintainer. Thank 
you for your patience.

I don't understand why a direct getItem() call to CustomerUserSource 
would trigger the WITH...COMPUTE line, while just doing getItem() on 
the LoginManager doesn't? As I understand it, getItem() calls each 
UserSource, so why would there be a difference in behavior?
