org-capture templates with file+olp target

[Erik Iverson <eriki@ccbr.umn.edu>]

Hello,

Using latest org-mode from git.

I'm trying to set up a simple org-capture template, to write
to a file test.org.  The first two lines below simply
define a path to some org mode file.

My confusion with the template is when I invoke org-capture --
I have it set to C-c c --, and then hit `t`, everything works
as I'd hope. (the file+headline target)

But when I hit `b`, (the file+olp target), I get an error,
which I can avoid by hardcoding the filename instead of using
the org-test-file variable in that case.  I get the error:

find-file-noselect: Wrong type argument: stringp, org-test-file

from the org-find-olp function in org.el.

I tried to debug, and it looks like that variable is not getting
evaluated for some reason.  I'm sure it's obvious to someone,
but is there a way around this?

Hardcoding the path is actually problematic, since my org
files are passed around various machines using git/Dropbox,
and therefore the path is different depending on where I
am located.

Below is the simplest example I could come up with, just
create a ~/test.org file and try it out.

   ;; a path to some org-files
   (setq org-test-path "/tmp")
   ;; a specific org-file
   (setq org-test-file (concat org-test-path "/test.org"))

   (setq org-capture-templates
         '(("t" "Todo" entry (file+headline org-test-file "Tasks")
            "* TODO %?\n  %i\n  %a")
           ("b" "Buy" item (file+olp org-test-file "Stuff to Buy" "House")
            "")))
