Lose the "." - call children? like this: (children? c) and make sure you
can see the test-record.component namespace from your user ns (apart
from importing the record class).

Hi,
I'm testing the use of records in Clojure and I have some issues when
I try to call function of another namespaces from the record.
For testing purposes, I defined this record:
(ns test-record.component
(:use test-record.utils))
(defprotocol Hierarchical
"Protocol for tree."
(children? [node] "children?"))
(defrecord Component [parent children name]
Hierarchical
(children? [node] (an-utils-function node)))
And I declared this namespace:
(ns test-record.utils)
(defn an-utils-function
[c]
(println (:name c)))
Very simple, isn't it?
But when I run this code in a REPL, I get an exception:
user=> (import 'test_record.component.Component)
test_record.component.Component
user=> (def c (Component. nil [] "The Root"))
#'user/c
user=> (.children? c)
IllegalStateException Attempting to call unbound fn:
#'test-record.utils/an-utils-function
clojure.lang.Var$Unbound.throwArity (Var.java:43)
Can I use functions of another namespaces from a record's code?
Thanks.
