Webdav Javascript Error


I noted that on many versions above 6.3. When trying to open a LO document, spreadsheet etc. file on a mounted webdav drive (on Windows 10 21H2), I get the following error messages:

This application requires JavaScript for correct operation. Please enable JavaScript and reload the page. 
    • App not installed: 
Nextcloud – a safe home for all your data

LO is supposed to just open and read the file, I can't make out what is happening here? Javascript? 

Once you move the file to a hard drive everything works OK. The fact that the file is on a webdav devices make LO do bizarre things. Please advise.

Could you try this:
- https://wiki.documentfoundation.org/QA/FirstSteps#Corrupted_user_profile
- upgrade to LO 7.3.1
From 7.3 versions, Webdav part is dealt internally completely differently.
Comment 2 SteGil 2022-03-10 04:57:24 UTC
Hi, I tested it on a brand new install of Windows 10 21H2 with no other programs installed and the latest LO msi. It looks to me like a collision between LO now featuring distant files and a Webdav drive already mounted. LO seems to believe  that the Windows mounted drive was mounted by LO itself...
Comment 3 Julien Nabet 2022-03-10 08:15:32 UTC
When you're talking about "latest msi", do you confirm you used 7.3.1 or did you download last LO version from 7.2 branch so 7.2.5 ?
(see https://www.libreoffice.org/download/download/)
Comment 4 SteGil 2022-03-10 08:25:10 UTC
I used the 7.3.1_win_x64.msi, the same phenomena show up on 7.2.5 and which I tried earlier
Comment 5 Julien Nabet 2022-03-10 09:21:13 UTC
Thank you for the feedback.

Michael: thought you might be interested in this one since it concerns Webdav and reported has also tested 7.3.1
Comment 6 Michael Stahl (allotropia) 2022-03-10 10:54:05 UTC
"file on a mounted webdav drive (on Windows 10 21H2)" - this means you use Windows Explorer to mount the webdav drive?

LO sees it as a local file then, any problem in accessing it is likely between Windows and the server.

to use LO's built in Webdav support you need to use File->Open Remote... dialog.
Comment 7 SteGil 2022-03-15 23:10:34 UTC
No, the mount is done via net use N: .....
Comment 8 SteGil 2022-03-15 23:13:10 UTC
Forgot to mention: other programs such as Notepad, Acrobat etc. have no problems opening files on a mounted webdav drive, LO 6.3.x neither.
Comment 9 SteGil 2022-03-15 23:14:32 UTC
.. and it's not just a single PC, we tested it in a school on at least 10 different PCs.
Comment 10 Julien Nabet 2022-03-16 19:15:12 UTC
I don't use Webdav at all, can't help here=>uncc myself.
Comment 11 Stéphane Guillou (stragu) 2023-03-30 12:04:33 UTC
I can't reproduce in Ubuntu 20.04 with:

Version: / LibreOffice Community
Build ID: e114eadc50a9ff8d8c8a0567d6da8f454beeb84f
CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: threaded

Using and ODT on a webDAV drive mounted in the GNOME file explorer. I could open, modify and save without error.

No repro either with a recent master build:

Version: (X86_64) / LibreOffice Community
Build ID: 9c7d3ce813c761b116232bc291e2737c59d383da
CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: threaded

SteGil, could you please:
- try with version 7.5.2, which received some webDAV and curl updates
- paste here the information from Help > About LibreOffice if you can still reproduce the issue

Thank you!
