Error while trying to auto-complete via ac-cider

[prateekbhatt]

I am trying to setup ac-cider and have added the following to init.el :

(require 'ac-cider)
(add-hook 'cider-mode-hook 'ac-flyspell-workaround)
(add-hook 'cider-mode-hook 'ac-cider-setup)
(add-hook 'cider-repl-mode-hook 'ac-cider-setup)
(eval-after-load "auto-complete"
  '(progn
     (add-to-list 'ac-modes 'cider-mode)
     (add-to-list 'ac-modes 'cider-repl-mode)))

However, while typing any symbol, I get the error (e.g. while typing remo):

Company: backend company-capf error "Not a nREPL dict object: remove" with args (candidates remo)

I have a suspicion it is Emacs25-related. Unfortunately I don't plan to look into Emacs25 compatibility until it hits at least a few major repos.

[prateekbhatt]

Ok, thanks.

I get this error as well with latest cider 0.15.0-SNAPSHOT and emacs 24.5.1.

[arichiardi]

I am not an emacs expert but it looks like this happens because this line cannot find 'dict as first item in the list of candidates. At this point I don't know where to touch but commenting out the second clause solves.
