Hello all,

I created a VM, installed Emacs 26.2 fresh, and installed various versions
of org-mode using the tar.gz files from https://orgmode.org/

I replaced org-mode in /usr/share/emacs/26.2/lisp/org with various older
versions until I found the version of org-mode that breaks the helm tags completion.

I found that the latest version of org where the feature works is Org-mode version 9.1.9.

Oops - my aplogies - I assumed that the org-versions stopped at 9.1.9.  I tested Org 9.1.14 which (to
my knowledge) is the last of the 9.1.X versions, and Org 9.1.14 works correctly.

I tested Org version 9.2 and Org version 9.2 is the version that breaks the tags functionality
from Helm.



I will spelunk around in the code to see what might have changed the behavior - if anyone has
suggestions or doesn't have this problem with an older version of org, please let me know - it could
easily be something that I have set incorrectly.

Thanks,

Hello all,

I'm hitting this problem with Org-mode 9.2.5:

Problem synopsis:  When I use org-set-tags on a heading
with no tags, Helm gives me the correct prompt w/a list of all my tags.
After I have entered a single tag, then no more Helm suggestions are
offered.  This is the bug, and it was fixed at some point.

Helm + org-mode *work correctly* when I run emacs using
the elpa/helm-20190726/emacs-helm.sh script which comes with Helm
for debugging purposes.  I notice that the org-version in the *working* example
is 9.1.9 (which is, I presume) the stock org-mode that comes with Emacs.

I have reproduced this problem on both Linux and OSX.

Can anyone suggest a next step to take?

Thanks,
