> What's happening in the ActionListener code?
Actually this is more a question of how does load-file work I believe.
If I run your example with (read) added to the end to prevent the main
thread ending from the command line:
clj test.clj
it works as expected... ie: ok gets printed when clicking.
However if I load your example at the REPL, I get your unexpected
behavior.
Additionally, without load-file in your example it works fine at the
REPL also:
(import '(javax.swing JButton JFrame)
'(java.awt.event ActionListener))
(def a (ref nil))
(let [frame (JFrame.)
button (JButton. "Click Me")]
(.addActionListener
button
(proxy [ActionListener] [] (actionPerformed [evt] (println @a))))
(doto frame
(.add button)
(.pack)
(.show)))
(dosync (ref-set a "hi mum"))
I'm stumped as to why load-file seems to behave differently from
command lane to REPL.

Tim.
