In the relatively short time of using clojure, I'm a little frustrated
with it's limited information the stack provides. I'm assuming
there's something I just don't know or am not doing. Many times when
I do something wrong, I have to read through the stack which sometimes
just says there's an error at line 0, which doesn't help me much.
For something like this, I'm seeing a cast exception, which I assume
has something to do with the proxy. Reading the docs on proxy, I feel
like I understand it correctly as I've used it to setup mouse
listeners before. In java the compiler might complain that a given
function isn't implemented. In clojure, I read that an
UnsupportedOperationException would be thrown should that
unimplemented function be called, which isn't happening here.
(import '(javax.swing JTable) '(javax.swing.table TableModel))
(def table (new JTable((proxy [TableModel] []
(getColumnCount [] 10)
(getRowCount [] 10)
(getValueAt [row column] (* row
column))))))
java.lang.ClassCastException: clojure.proxy.java.lang.Object
$TableModel (NO_SOURCE_FILE:2)
Could someone point me to what the problem is here in this code? Or
more specifically how to debug this better in the future.
