It's just a stylistic thing, but most people have stopped using the
"." standalone operator and moved to (.addActionListener isoButton)

You are trying to provide the definition of the "actionPerformed"
method of the ActionListener, but you haven't actually specified that
that is what you are doing.

I think you want something more like the following, but I don't know
what AddActor, RemoveActor and isoActor are supposed to be.
(.addActionListener isoButton
(proxy [ActionListener] []
(actionPerformed [] (if (.isSelected isoButton) (AddActor
isoActor) (RemoveActor isoActor)))))
