I created a minimal example from a chestnut project:
https://github.com/sveri/freactive-example
The relevant stuff happens in core.cljs and session.cljs. When you run the
application, add some text to the input and then click the button, the input is
rerendered, which is unexpected from my side.
I hope that shows the problem I have.
Best Regards,
Sven
