@SessionAttributes doesn't get removed in Spring Portlet MVC

[cptan_alatriste]

I have a simple Portlet that I expect to take some user input, do some stuff and show a success message. The code goes like this:

@Controller(value = "myController")
@RequestMapping(value = "VIEW")
@SessionAttributes("myCommand")
public class MyController {

    @ModelAttribute("someList")
    public Map<String, String> getSomeList() {
        return theList;
    }

    @ModelAttribute("myCommand")
    public CambioPlanCommand getCommandObject(PortletSession session,
            Principal principal) throws SeguridadMiClaroException {
        MyCommand command = new MyCommand();
        return command;
    }

    @RenderMapping
    public String showView() {
        return "myView";
    }

    @ActionMapping(params = "action=stuff")
    public void doStuff(
            @ModelAttribute(value = "myCommand") MyCommand datosFormulario,
            BindingResult bindingResult, SessionStatus status,
            PortletSession session, Principal principal, ModelMap modelMap,
            PortletRequest request) {

            modelMap.put("theMessage", "Stuff is done");
            status.setComplete();


    }

}

The first time I execute the Portlet everything goes fine: The command object gets populated, the message is put in model and my JSP shows it in screen. Then I go to another page to play with some other portlets; and when I return to my original Portlet I expect the following:

- To get an empty instance of MyCommand
- To see no Message in Screen

But I find the opossite, and I still see the message configured in the previous request. I'm very confused about this, since the Message was not configured as a SessionAttribute (only the command) and I called SessionStatus.setComplete() so if everything was stored in Session it should already be removed.

Any ideas?
