org-element--cache: Warning(izt.org): Got element without parent (cache active?: t)

org-element--cache: Warning(izt.org): Got element without parent (cache active?: t)

[Gregor Zattler]

Dear Ihow, I caught another org-element-cache warning.
I started Emacs (after having problems with a botched
configuration, which in turn uses babel...) and called
the agenda like so:

  (defun gz/org-agenda-list ()
    "Show Org Agenda starting yesterday."
    (interactive)
    (org-agenda-list 0 "-1d")
    (beginning-of-buffer)
    (org-agenda-goto-today))

and then I got this (see below).  This is with

GNU Emacs 30.0.50 (build 1, x86_64-pc-linux-gnu, cairo version 1.16.0) of 2023-08-22
Org mode version 9.7-pre (release_9.6.7-721-g53c9d9 @ /home/grfz/src/org-mode/lisp/)

Thanks for speeding up org-mode, Gregor

This is very strange. The error originates from a check in
`org-element--cache-verify-element' that only triggers when cache is
enabled, but I do not see node-property being recorded in the cache. I
am not sure how this could ever be possible.

May you try to reproduce the problem starting from emacs -Q, reducing
your Org file to some small file that can be shared?

that happened when org-mode generated my agenda, there
are four rather big org-mode files involved.  Is it
sufficent to try to reproduce with izt.org only, which
is mentioned in the warning?

I tried just now, but there was no warning and since
the warning I changed the file.  Especially I did
org-link and resolved all problems...

Next time I will save the file immediately for
inspection.

Ciao; Gregor
