Can't follow links with id property

Can't follow links with id property

[-- Attachment #1: Type: text/plain, Size: 770 bytes --]

Hi everyone,

I can't follow links with an ID property. I have attached a minimal
example org file. Org complains it cannot find a match and prompts to
create a new headline. Answering yes to the prompt creates a new
headline like this:

* id:9dfdc23e-f9ce-413b-b950-fc20fd152e42


Debugger entered--Lisp error: (error "No match")
  signal(error ("No match"))
  error("No match")
  org-link-search(#("id:9dfdc23e-f9ce-413b-b950-fc20fd152e42" 0 39 (org-attr nil)) nil 119)
  eval((org-link-search #("id:9dfdc23e-f9ce-413b-b950-fc20fd152e42" 0 39 (org-attr nil)) nil 119))
  byte-code("~\210\301\b!\207" [cmd eval] 2)
  org-open-at-point(nil)
  call-interactively(org-open-at-point nil nil)

* B oscillations

The oscillations can be smeared:
+ convoluted with the [[id:9dfdc23e-f9ce-413b-b950-fc20fd152e42][acceptance function]]
+ further enhanced by detector resolution effects (e.g. time resn).


* Acceptance
  :PROPERTIES:
  :ID:       9dfdc23e-f9ce-413b-b950-fc20fd152e42
  :END:

In LHCb acceptance is a function of (proper?) time (B decay time / B
decay length / PV-SV distance). Combined effect of,
+ non-uniform geometrical acceptance (as LHCb is not hermetic)
+ and triggering on a min. time interval (or displacement) from IP/PV.
  Ensures a long lived B.

I can not reproduce that with your minimal example with
Org-mode version 7.6 (release_7.6.120.g0b9c.dirty) on
GNU Emacs 23.3.1 (i486-pc-linux-gnu, GTK+ Version 2.24.3) of 2011-04-10
on raven, modified by Debian

I tried it again, still present with both Emacs 23.2 and Emacs 24.

Org-mode version 7.6 fe0c013965bc5a15309cec2e4ab4ad78689bc4af
GNU Emacs 23.3.1 (i386-mingw-nt5.1.2600) of 2011-03-10 on 3249CTO

I confirm Suvayu's bug.

I clicked with the mouse on the link. The backtrace follows.
cheers,

For the record, exporting to HTML has a properly functional link. Just
org-open-at-point doesn't work in the orgmode buffer.

I cannot reproduce this with Emacs 23.3 and 24.0.50.

Do you have any setup wrt ids?  (C-h v org-id-*)

Or maybe your method for generating ids changes between the 
moment your created this one and the moment your tried to
open it?  

Thanks for further information,

I don't have any org-id related customisations. This is the first time
I am trying them out. :-p

When I tried to replicate this, I got the same behaviour as before. Then
I tried creating the ids again (with org-id-get-create) and tried
following the links and it worked!

So far this is what I have figured out. If you
1. create the ids
2. link to it
3. try to follow the link (all in the same session)
everything works. But now if you save the file and reopen it in a new
session and try to follow those same links, it fails with the error I
reported earlier. Now if you call org-id-get-create on the linked
headline and go back to the link and try to follow it again, it works as
expected! I think org-id-get-create does something that resolves the
problem. So maybe the issue is with `org-open-at-point'.

Hopefully this is more consistently reproducible.

PS: I tested starting with emacs -Q -l ~/.emacs.d/minimal-org.el
