helm-dash can't open result entry.

[stardiviner]

I have Emacs version 25.0.50.2 And use the latest helm-dash from el-get.

And have this configuration.

(require 'helm-dash)

(setq helm-dash-docsets-path (expand-file-name "~/.docsets")
      helm-dash-min-length 3
      ;; helm-dash-completing-read-func 'completing-read ; 'completing-read, 'ido-completing-read
      helm-dash-browser-func 'browse-url ; 'browse-url, 'eww
      ;; helm-dash-connections
      helm-dash-common-docsets '("Ruby" "Ruby on Rails"
                                 "Python 3"
                                 "HTML" "CSS" "JavaScript" "CoffeeScript"
                                 "Common_Lisp" "Clojure"
                                 "C" "Go"
                                 "SQLite" "MySQL" "Redis" "MongoDB"
                                 "Qt"
                                 "Vagrant" "Nginx"
                                 "Android"
                                 "RubyMotion" "AngularJS"
                                 )
      ;; helm-dash-docsets
      )

And when I press Enter on result entry Ruby Kernel.autoload. Then this error raised.

Hi @stardiviner, we're trying to reproduce your error locally. I'll reply you soon

[kidd]

FYI: I couldn't reproduce it in 24.

[areina]

me neither in emacs 25.0.50.1

Could be something related with helm? @stardiviner could you confirm that you're using latest versions of helm and helm-dash? thanks

[stardiviner]

I found the reason.

  (define-key helm-map (kbd "<RET>") 'helm-maybe-exit-minibuffer)

  ;; NOTE: this cause helm-dash open menu candidate error.
  ;; (define-key helm-map (kbd "<return>") 'helm-confirm-and-exit-minibuffer)
