I'm hazy on what the variety of events is.  HTML supports PUT
and POST, and Javascript supports purely local validation, and
Ajax can support round-trips to the server.

Did you have something else in mind ?  Such as interdependencies
between widgets (if X is "Y" then disable Z) ?

Typically, each widget should be able to respond to certain events:
* "onClicked", "onEnabled", "onDisabled" for a button
* "onExpand", "onCollapse", "onSelect", ... for a tree
* "onGetItems", "onSelect" for a combobox
* etc

This is normally done with a tree of widgets (in Swing), where core events are captured by listeners (which are for instance more functional widgets. These widgets can then themselves support new event types that are specific for them. This is the model that Wicket uses. I'm not sure it makes total sense in the context of RIFE and if the same design should be applied, which is why I'm soliciting input.
