[Seaside] WASystemConfiguration - rendering a button?

Hi John,

A good question... that's not something we've explicitly supported
before. Off the top of my head, one solution might be to create some
kind of CommandAttribute that you could add to your application's
SystemConfiguration subclass. Then you'd need to add a method to
WAUserConfigurationEditorVisitor that could render a button for that
new attribute type. It would be a bit weird, because I guess the
attribute would ignore any value it received.

Probably the better solution, since this isn't really a
"configuration" thing, would be to extend the admin UI to be pluggable
in some other way to provide admin commands. It could call a method on
the Application/Handler, or look for methods marked with a certain
pragma, or you could even have a configuration attribute that
specified a command class (or a list of command classes) or something
(though that may be irritatingly overkill). I would love to see the
web-based admin console expand to be more useful, and it's possible we
could look at integrating something you did in this direction, but it
won't come from us before 3.0 comes out.

Or, the simplest solution, create an admin component for your
application and register it at a different path. :)
