Mail: Cannot open parent folder, subfolders are expanded instead

[reuterbal]

Expected behavior

Imagine a folder structure like this

--+-- ParentA
  |-- ParentA.SubA
  |-- ParentA.SubB
----- ParentB

1. Clicking on ParentA opens the message list in that folder
2. Clicking on the "Expansion triangle" in front of ParentA expands the list of subfolders
3. Clicking on ParentA.SubA opens the message list in that subfolder
4. Clicking on ParentB (without subfolders) opens the message list in that folder

Actual behavior

1. Clicking on ParentA expands the list of subfolders, message list is not shown
2. Clicking on the "Expansion triangle" in front of ParentA expands the list of subfolders
3. Clicking on ParentA.SubA opens the message list in that subfolder
4. Clicking on ParentB (without subfolders) opens the message list in that folder

I.e., Parent folders with subfolders cannot be opened, all other situations work fine.

1. Clicking on `ParentA` expands the list of subfolders, message list is not shown

Does the URL change in that step? Could you inspect the href on the list item?

[reuterbal]

The URL stays the same, however href seems to be correct: I can right-click and "Open in a new tab" which yields the message list.

I'm experiencing the same issue over here:

• If a folder has sub folders, the content of parent folder is just not shown.
• URL does not change in this step. Only the very last folder will show content (having the URL changing).
• Folders with no subfolders change URL and work flawlessly in listing

This is what href looks like on the inbox folder (containing a favorites folder):
<a href="/apps/mail/#/accounts/4/folders/SU4FR2e=" class="icon-inbox"><!----> inbox </a>

The URL stays the same, however href seems to be correct: I can right-click and "Open in a new tab" which yields the message list.

I can confirm that this workaround actually works. Thanks for the hint!

Same Mail version (0.17.0), same nextcloud version (16.0.5) -> same issue.

Open in a new window/tab is in fact a working workaround, but far from perfect.

Anything else you might need to debug this issue?

Time. I'll try to allocate some this week, but there is a lot on my plate right now. If any dev has time to take a deeper look I'd be very thankful :heart:

I'm havin gthe same issue on my instance using 0.17.0, but it works find on my dev instance with master.

[ChristophWurst]

Tested with the help of a test account from @nickvergessen and we found out that this was fixed recently. Latest master does not have this problem anymore and the latest stable releases for Nextcloud 17 should also be fine :)

[reuterbal]

Sorry to bother again: I updated to NC 17.0.0 and the problem still persists with Mail 0.17.0. Thus, the latest stable doesn't seem to have the fix, yet.

[ChristophWurst]

Okay, then sorry for the confusion. Master will be released today most likely, so the fix will follow shortly :)

[reuterbal]

Can confirm: After update to 0.18.0, the issue is gone. Many thanks!

[ChristophWurst]

Awesome! Thanks for the feedback!
