display two same chart panel at once

[jrlj]

When I run the demo codes, it always open two same chart panel at once, why?

I've never seen that before. Can you take a look at the Atom developer console for errors? You may also want to try restarting Atom.

I'm also getting this.

Steps to reproduce

• Run

  lein new repro
  cd repro
  atom --clear-window-state .

• Add deps to project.clj

  [proto-repl "0.3.1"]
  [proto-repl-charts "0.3.2"]

• Open src/repro/core.clj
• Replace contents with:

  
  (ns repro.core
  (:require [proto-repl-charts.table]))

(proto-repl-charts.table/table "table" [[1 2] [3 4]])

- Start repl with `ctrl+, l`
- Eval with `ctrl+, f`

This gives me two panes with the table:

The dev console is empty.

Well, it seems to be intermittent. I was able to reproduce several times with the above steps, but now, following the same steps, it works. :(

TLDR: Remove cider-nrepl and it works.

After some hours of debugging, i found that I had the cider-nrepl enabled in my .lein/profiles.clj. Cider adds an extra message (changed-namespaces) in the nrepl-reply. This message comes after the status: done message, which the nrepl-client used by proto-repl doesn't expect.

For every message after done, it will send the whole list of messages to the callback again. This can probably be considered a bug in the nrepl-client. The relevant code is here:
