[O] symbol's function definition is void: org-find-property

[童俊翔]

I want to use capture, the following is my configuration in .emacs


;;(add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))
(global-set-key "\C-cl" 'org-store-link)
(global-set-key "\C-cc" 'org-capture)
(global-set-key "\C-ca" 'org-agenda)
(global-set-key "\C-cb" 'org-iswitchb)

;;capture template
(setq org-capture-templates
  '(("t" "Todo" entry (file+headline "~/360Cloud/GTD/gtd.org" "Tasks")
         "* TODO %?\n %i\n %a")
        ("j" "Journal" entry (file+datetree "~/360Cloud/GTD/journal.org")
         "* %?\nEntered on %U\n %i\n %a")))

When I press C-cc, j,  it doesn’t work, and i promoted that: symbol's function 
definition is void: org-find-property.
What’s the problem?
Thank you for your help!
