Mail: Subfolders are not expandable/collapsible (fix 606)

[omocinteractive]

Steps to reproduce

1. Open Mail-App
2. Click on "Show all folders"

Expected behaviour

open folders

Actual behaviour

not open folders only changing text to "close folders"

Nextcloud 12.0.4

Mail app

**Mail app version: 0.7.9

**Mailserver or service: own server with plesk, webmail horde, courier imap, postfix

Fix #606 with z-indx is not working. Workaround:

delete &.collapsible:not(.open) { > ul, > .folders {...} on line 851

I have the same issue on a fresh OC13 installation with Mail 0.7.9. I noticed though that if I click the "show all folders" the drop down actually has items it's just they are not visible (though examining via Firefox's developer tools clearly show the folders are there). I can also click the invisible items and the respective folders load.

Addendum 1: observed so on a Linux client with Firefox 58.0.1
Addendum 2: same issue happens on Android with Firefox 58.0.1

... i replaced all files, cleared my cache and tried it on different browser - allways the same. see my configuration issue template for details. what kind of information do you need exactly? i think it is a problem with js/css (see my workaround - the folders have been loaded but js/css don't show them). i disabled pagespeed-mod also and other apache-mods (because of js-problems in nextcloud and other projects).

[ChristophWurst]

Any errors in your js console?

[omocinteractive]

... no errors!

[skjnldsv]

You need to clear your appdata server cache. @rullzer? 😂

[omocinteractive]

... do you have a short tip or little how-to for me, please? i found nothing for clearing app cache under nextcloud.

[skjnldsv]

@omocinteractive sorry, you can try the dedicated app rullzer made here :
https://github.com/rullzer/appdatacleaner

Then use the occ command line to clear css and js! :)

[omocinteractive]

... thx a lot! i will try it on weekend :)

[omocinteractive]

... sorry, nothing happend. i think it is'nt a problem of caching (see @zpuskas posting - fresh installation). i merged the output css file - it is exactly the same. i will wait for new versions, maybe some day it will work. and - if it is a problem of caching - there is a generally problem with nc updater, i think ...

Hey @omocinteractive,

are you using a mailserver that has an INBOX prefix? There are known bugs with those. Try clicking the inbox icon and its subfolders will magically expand 😉

[omocinteractive]

ARRRRGH - 10.000 kisses :) Yes, my mailserver use an INBOX prefix! Thx a lot!

Now that I understand the problem, I'm pretty sure this is a duplicate of https://github.com/nextcloud/mail/issues/386
