Error using with-fsm macro. Use of undeclared state variable #5

Open nyemiks opened 5 months ago

nyemiks commented 5 months ago

I am unable to run the default example from the documentation

(defn form [] (rs/with-fsm [state global-image-fsm] (r/with-let [ text (r/atom "") update-text #(reset! text (-> % .-target .-value)) ] [:div [:input { :type :text :on-change #(update-text %) :on-focus #(re-frame/dispatch [::edit-started :validation-open]) :on-blur #(re-frame/dispatch [::edit-ended :validation-open]) } ] ] ) ) )

I get the below error trace

There is a problem with the with-fsm macro. I have no idea why this error happens. I was able to use the low level api to get it to work but in my own opinion the with-fsm macro looks more high level.

What is missing in the above code ?
