Could this be a figwheel issue? - http://stackoverflow.com/questions/36735665/why-do-i-get-this-clojure-exception-cant-change-establish-root-binding-of

my project.clj says:

how do I run my own server and retain figwheel’s functionality then?

it’s simple

all figwheel does is provide a websocket server

so if you’ve got a Clojure server running on localhost:5000

and a figwheel server running a localhost:3449

but the clojure server is serving up the compiled JS from the figwheel process

you can go to localhost:5000 and the figwheel JS in the browser will still get all that sweet websocket goodness

@nooga:

I see
