this works

(e/defn Foo []
  (e/server
    (let [k (e/watch !k)]
      (dom/div (dom/text (case k :a "A" :b "B" "NONE"))))))

(e/defn Main [ring-request]
  (e/client
    (binding [dom/node       js/document.body
              e/http-request (e/server ring-request)]
      (dom/div (Foo) (Foo)))))

The original problem occurred in my project. Re-arranging case to execute on client like here seems to fix it:

(e/client
  (case (e/server (::menu state/session))
    ::menu.some-page
    (e/server (SomePage <some-server-state>))
    ::menu.some-other-page
    (e/server (SomeOtherPage <some-server-state>))
    (e/amb)))

I can repro this. Definitely a bug. We'll keep you posted

to keep you posted, this relates to an internal bug we're in the midst of fixing. No ETA yet, the change is in the internals and therefore requires careful planning and testing

Okay. I appreciate all you guys works!

In the following example, when I alternate !k between :a and :b, the dom divs keep building up instead of being unmounted by case. Am I'm missing something?

(ns electric-starter-app.main
  (:require [hyperfiddle.electric3 :as e]
    [hyperfiddle.electric-dom3 :as dom]
    [electric-starter-app.two-clocks :refer [TwoClocks]]))

        :a (dom/div (dom/text "A"))
        :b (dom/div (dom/text "B"))
        (dom/div (dom/text "NONE")))))

  (e/defn Main [ring-request]
    (e/client

                e/http-request (e/server ring-request)]

          (e/server
            (dom/div
              (Foo) (Foo)))))))

(defn electric-boot [ring-request]
  #?(:clj  (e/boot-server {} Main (e/server ring-request))  ; inject server-only ring-request
     :cljs (e/boot-client {} Main (e/server (e/amb)))))     ; symmetric – same arity – no-value hole in place of server-only ring-request

Thanks for the report. We're out at reclojure but we will take a look at this once we're back. Are you running on latest?

Thank you! Yah. Same date as one on Clojars. Deleted ~/.m2 cache and tested the snippet on fresh starter app project.
