Magriite question?

I'm trying to use Magritte for a "buddy list" app. I've defined Buddy using Magritte (i.e., using description* class-side methods). One of the buddy attributes is userName. When I bring up an editor for a buddy (using #addValidatedForm) I would like to be able to select a userName (from those in the system) and have the remaining attributes filled in automatically. But each attribute is uniquely associated with a description* method and there doesn't appear to be a way to define an action (associated with selecting a userName) that would allow me to define the other buddy attribute and have them appear in the editor.

descriptionUserName

^ MASingleOptionDescription new
options: ((MMADatabase users collect: [ :each | each userName ]) asArray);
selectorAccessor: #userName;
label: 'User Name';
priority: 1;
default: 'N/A';
undefined: 'N/A';
yourself

There are different ways to get around this. MASingleOptionDescription
uses MASelectListComponent as its default view. You can for example
create a custom subclass of MASelectListComponent and select that as
the #componentClass: of your description.

Alternatively you can also compose the ready-made Magritte component
with a normal Seaside component, that provides the functionality (e.g.
a button) to add new buddies.
