Any idea why figwheel-main + lein + nodejs + re-frame doesn't want to cooperate with me? I can't say I understand what the stacktrace is trying to tell me.

1.0.0-rc2

(defn register-handler
  [kind id handler-fn]
  (when debug-enabled?                                       ;; This is in a separate when so Closure DCE can run
    (when (and (not (settings/loaded?)) (get-handler kind id false))
      (console :warn "re-frame: overwriting" (str kind) "handler for:" id)))   ;; allow it, but warn. Happens on figwheel reloads.
  (swap! kind->id->handler assoc-in [kind id] handler-fn)
  handler-fn)    ;; note: returns the just registered handler

Seems to be the important bit

What’s line 67 of registrar.cljc?

deadghost19:09:32

Bumped re-frame to 1.1.1 and that did it! 👏 Thank you. I was stuck on this for days. How did you go from registrar.cljc to suspecting the re-frame version? Seems like a big leap.

lilactown19:09:27

I looked at the code on GitHub and there’s no line 67 in the latest lol

Didn’t know what was wrong but figured we would need to see what changed to figure it out. Glad upgrading just worked
