I have code like (defn ^:export main[] (let [eb (vertx.EventBus.)] (set! (.onopen eb) #()) eb)) unfortunately it end up with compilation error: Assert failed: set! target must be a field or a symbol naming a var targetexpr Whats the problem? I am using lein (1.7.1) + lein-cljsbuild (0.2.5). -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: ClojureScript compilation error
punting here, I haven't use set! in a long time. but if onopen is a field - use field access (.-onopen...)

Operators with appending ! are noted as special clojure.core= (doc set!) - set! (set! var-symbol expr) (set! (. instance-expr instanceFieldName-symbol) expr) (set! (. Classname-symbol staticFieldName-symbol) expr) Special Form Used to set thread-local-bound vars, Java object instance fields, and Java class static fields. Please see http://clojure.org/vars#set nil clojure.core= __ You would write : (def eb (atom ())) (defn ^:export main[] (let [eb (vertx.EventBus.)] (reset! eb #()) eb)) ?
