I have just started using org-collector so . . .

org-collector works as expected using

GNU Emacs 24.4.1 (i586-pc-linux-gnu, GTK+ Version 3.14.5)
of 2015-03-07 on binet, modified by Debian
Org: 8.2.10 release_8.2.10

but fails if

GNU Emacs 24.4.1 (i586-pc-linux-gnu, GTK+ Version 3.14.5)
of 2015-03-07 on binet, modified by Debian
Org: 8.3beta release_8.3beta-1030-g65bbb1

As I reported yesterday my first attempt to use collector was using 
8.3beta, etc.

When using the 8.3beta release, I evaluated the example downloaded from
orgmode.org/worg/org-contrib/org-collector-example.html 
<http://orgmode.org/worg/org-contrib/org-collector-example.html>
All columns except ITEM evaluated to the default error. The ITEM column 
does evaluate as expected.

I (usually) download daily the recent org-mode version from git to my 
directory at /usr/share/emacs/site-lisp/org-mode.
In my .emacs I commented out (add-to-list 'load-path 
"/usr/share/emacs/site-lisp/org-mode/lisp")
and left
(add-to-list 'load-path "/usr/share/emacs/site-lisp/org-mode/contrib/lisp")

org-collector worked as expected,without the 8.3 beta version. (8.2.10 
was loaded by default)

As an exercise I searched ORG-NEWS 8.3 and 8.2 for collector, table, 
orgtbl, dblock. Having just started to learn emacs lisp I had no idea if 
any changes mentioned would have affected org-collector.

Thanks for listening.
