what in fact did happen.  You don't know how to make a good report?  See

When I try to edit a property in column view, I get the following error message:

Invalid column specification format: nil

This only seems to happen if the point is not too close to the left
margin.  I did a bit of digging and found out that the culprit is most
probably the `org-columns-update' function, which contains this:

(let* ((spec (nth (current-column) org-columns-current-fmt-compiled))
...) ...)

Since `org-columns-current-fmt-compiled' seems to contain one entry per
_table_ column and `current-column' returns the "horizontal position of
point" (i.e., the index of the _character_ column the point is in),
`spec' gets assigned nil unless the point happens to be no more
characters from the left margin than there are columns in the column
view, and even then it gets assigned the wrong thing.

I might be mistaken, though - I only skimmed through this code.

Here is an example file where this happens:

--8<---------------cut here---------------start------------->8---

* Test
** Entry A
:PROPERTIES:
:a:        1
:b:        2
:END:
** Entry B
:PROPERTIES:
:a:        3
:b:        4
:END:
* Config
#+COLUMNS: %4a %4b
--8<---------------cut here---------------end--------------->8---

Go to `* Test', press `C-c C-x C-c', then go to `2' and press `e 2 <RET>'.

I also saw this on emacs -Q, with the built-in Org-mode:
