[Orgmode] Bug: editing priority in column view

[Wanrong Lin]

Hi,

I have a column view configuration like this:

(setq org-columns-default-format (format "%%%iITEM(Task) %%10TODO 
%%20SCHEDULED %%1PRIORITY(P) %%TAGS(TAGS) %%6Effort(EST){:} 
%%CLOCKSUM(CLK)" (- fill-column 24)))

And I have a org-file "Test.org" with following entry:

* TODO Test1
*** TODO Test2
   SCHEDULED: <2009-02-19 Thu>

If I run "org-agenda-list", and then "org-agenda-columns", and then move 
the cursor to the "P" field of "Test2" line, press "e", and then press 
"a" in minibuffer, things are strange now:

1. At first, it worked fine. I could see "Test2" has priority "A" in 
both the agenda buffer and the "Test.org" buffer.
2. I manually removed the "[#A]" in the "Test2" line of "Test.org" 
buffer, saved the file and KILLED the "Test.org" buffer
3. In the agenda buffer (still in column view), I pressed "g" (to 
refresh). I could see "Test.org" was reopened in a buffer.
4. Now I redo the priority editing in the agenda buffer, nothing changed 
in the agenda buffer, and after examining "Test.org" buffer, I found the 
priority "A" goes to the parent item "Test1". So I got this in the 
"Test.org" buffer:

* TODO [#A] Test1
*** TODO Test2
   SCHEDULED: <2009-02-19 Thu>

It seems the order of file opening and column view creation will affect 
org's behavior.

I am using 6.22b, the latest release.
