Hey,
I figured it out. Fun puzzle. ;)
As expected core.async is not the real villain here, the behavior sure is odd
but I'm not sure it is a bug.
The issue is that {:name test} inside a go block always gets turned into a
hash-map, while outside the better option array-map is chosen by the
I would actually consider this a core.async defect - the
interpretation of literals should not be different in go blocks. I
would open a core.async issue with all the details of this thread
summarized.

Hi Thomas,
I'd imagine it becomes even less obvious once you start using your app and at
some point assoc into an array-map, getting over the threshold and turning the
result into a hash-map. I'd imagine that would be really hard to track down.
Anyways, sorted-set seems to have all sorts of caveats.
So
Hi,
while I was preparing the bug report Captaion Obvious hit me again. This also
occurs in clojure:
As Thomas said, this is enough to reproduce it:
(def a (atom #{}))
(reset! a (into (sorted-set) [{:name foo}]))
(swap! a conj {:name bar})
- java.lang.ClassCastException:
Seems like a separate issue to me.

Maps aren't comparable, so they don't make sense with sorted-set. This is
not a bug.

Cannot say without the rest of the code but I what is in (:transformations
resp)? sorted-set doesn't work if one item doesn't compare to another (eg.
numbers vs maps).
Suppose:
(def a (atom #{}))
= (var user/a)
(reset! a (into (sorted-set) [1 2 2 2 3]))
= #{1 2 3}
(conj @a {:name test})
Hi Thomas,
the code I pasted was maybe a bit misleading.
Function one:
(defn save-transformation [_]
(go (let [trans-name (hel/get-value transformation-name)
[ok _] (! (hel/post-async-ch /cvs/save-transformation
{:name trans-name
That code doesn't help much either since there is still no way to tell what
sess/transformations-cur is.
I'd suggest printing the value before trying to swap! it, I see no reason
anything in there would confuse core.async.
(defn save-transformation [_]
(go (let [trans-name (hel/get-value
Hi Thomas,
Thanks for taking the time to answer me.
Ok, this is the session namespace, reduced to the relevant parts:
(ns de.sveri.structconverter.session
(:require [reagent.cursor :refer [cur]]
[reagent.core :refer [atom]]))
(def state (atom {:cur-csv-page nil :files []
