I am trying to learn how to use session attributes, but I have a problem removing them from session.
I want to remove only one attribute from session, but using status.setComlete() removes all my attributes from session.
I have been searching how to do it:

```
status.setComplete();       
request.removeAttribute("listaMaquinasImportar", WebRequest.SCOPE_SESSION);

```

This removes all the attributes.
Is there a way to do this?

Thanks.
