[Cocoon+Avalon] Adding a new ComponentSelector

[Ugo Cei]

Hi People,
I'm trying to create a reusable component for use in Cocoon and in other 
applications, so I decided to create an Avalon component for this, 
called Authenticator. Since I need different components for the 
Authenticator role, I also created an AuthenticatorSelector.

Now I'm trying to use my component in a Cocoon action. This is a snippet 
of code from the "act" method of my Action:

    ComponentSelector selector = null;
    try
      {
        selector = (ComponentSelector) manager.lookup
          (Authenticator.ROLE + "Selector");
      }
    catch(ComponentException ce)
      {
        AuthenticatorSelector as = new AuthenticatorSelector();
        as.setLogger(getLogger());
        as.compose(manager);
        as.configure(conf);
        selector = as;
        // HOW TO ADD SELECTOR TO MANAGER HERE?
      }
The first time the action is invoked, the lookup method fails and a new 
selector is created, but I want that on the following invocations, the 
lookup method returns the previously created selector instance.

Is it possible? Is this the correct way of using Avalon selectors? I 
must confess that after having read two or three times "Developing with 
Apache Avalon", I still don't grasp most of it :).

        Thanks in advance and sorry for the crossposting,
                Ugo
