[Orgmode] org-refile: only works on leaves?

[Wanrong Lin]

Hi,

Another thing I found out when using org-refile is, it seems the filing 
target can only be the leaves of the outline tree. The non-leaf target 
locations will be displayed in the auto-completion buffer, but can not 
be selected.

I have the following settings

(setq org-refile-targets '((org-agenda-files . (:maxlevel . 2))))
(setq org-refile-use-outline-path t)

I am using the latest version (5.17a).

Is there any option that I can set to change this behavior? Thanks for help.

And, MERRY CHRISTMAS to all orgers....
