Org 9.7 agenda appears to not set `org-marker` property (causing our habit selector to not work) about org-super-agenda HOT 11 OPEN

@k11m1 Thanks. Until this is fixed, you'll have to either not use the habit selector, or use Org 9.6.

Please see https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=fac55324accbcab08dfebbde8295b2f1b4b9f45e, which demotes the error to a warning.

Hello,

I don't understand. Please start from the beginning and explain the problem in context. As well, please provide a minimal reproducible example. And, of course, include the versions of all relevant software. You know, all the standard bug-report info.

I think i have the same issue, at least removing habit fixes it:

Config in org-agenda-custom-commands:

        ("t" "test"
         ((agenda "" ((org-agenda-span 'day)
                      (org-super-agenda-groups
                        '((:name "Timeline"
                           :time-grid t)
                          (:habit t)
                          )
                       )))))

Shows without debug:

if: ‘org-element-at-point’ cannot be used in non-Org buffer #<buffer *Org Agenda(t)*> (org-agenda-mode)

Trace: https://gist.github.com/k11m1/fa6d819d247ef9e8b69d31bf0e659f2a

Removing (:habit t) makes the error go away.

I am using Latest doom emacs (as of 2023-09-25), on Arch Linux.

• GNU Emacs 29.1
• Org 9.7
• I am on: 4efc0bd * master origin/master replaced Meta: Update .gitignore

@alphapapa No problem. I am not using the habit selector actively so disabling it for me fixed all the problems.

Another option is to comment out the check in org-element.el that causes the issue.

Sure, just be sure to recompile that file afterward, otherwise you'll get reduced performance from its being interpreted.

The root cause is emacs-straight/org-mode@f135954.

Determining whether something is a habit will involve a call to org-element-at-point, which now errors when not in org-mode. This is normally not a problem, as agenda items processed in their home buffer in org-mode. But there's (at least) one exception: Hourly lines/separators in the time grid (like 10:00 .....) aren't real org items, and they're "processed" in the org-agenda buffer in org-agenda-mode.

The simple fix is to evaluate whether an item is a habit only (when (derived-mode-p 'org-mode)). See https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=a1fa52197 for a similar fix inside org.

I had a similar issue with a org-agenda-prefix-format that makes a call to (org-get-category).
