It's defined in my-re-frame.events

Great, have you required that namespace with an alias?

either at the REPL (require '[my-re-frame.events :as events]) or in the my-re-frame.core namespace definition (:require [my-re-frame.events :as events])

then at the REPL you should be able to type simply ::events/initialize-db without error. This should tell you if you got the key alias part right without worrying about re-frame.

thanks @U093DA4QY i have required events in core.cljs from where I'm dispatching event

do you get an error when evaling ::events/initialize-db in the REPL?

(ns my-re-frame.core (:require [my-re-frame.events :as events]))

now when i switch (in-ns 'my-re-frame.core) in figwheel repl and do (re-frame/dispatch-sync [::events/initialize-db])

events is undefined so, I think my understanding about in-ns is wrong

hmmm… it all looks right to me

maybe in your setup you need to load the namespace? have you tried (load-namespace 'my-re-frame.core)?

Interesting now i get error Unable to resolve symbol: load-namespace in this context

I think it has something to do with emacs and cider setup

because i have started figwheel from emacs cider

thank you very much @U093DA4QY!

I'm not sure in-ns actually loads the file

load-namespace doesn't exist in CLJS either

you can try (require 'my-re-frame.core) and then (in-ns 'my-re-frame.core)

Thanks @U4YGF4NGM, still it can't load that namespace getting error Invalid token: ::events/initialize-db

ahh stupid of me, now i have found why I am getting those errors in emacs in fighweel starts in clj cider

and it tries to find files with clj extensions

The answer to the question is: Use icon-menu. 🙂

they removed IconMenu in a never version of material ui, so if one looks at the examples of AppBar it might be confusing. If using old-material-ui.
