Newly created Nextcloud users do not show up in Chat list

This is a copy from https://help.nextcloud.com/t/javascript-xmpp-chat-missing-contacts/14408, so, as suggested there, I post it here.

Nextcloud version: 12.0.0 Operating system and version: Ubuntu 16.04 Apache or nginx version: 2.4.18 PHP version: 7.0.18 Is this the first time you’ve seen this error?: yes

Can you reliably replicate it? (If so, please outline steps):

The issue you are facing:

Other users, which are created afterwards, are not shown in the chat window ( JavaScript XMPP Chat with internal server). So, the first user (admin) sees no other contacts, second user only sees admin and so on.

I tried reinstalling the app, no changes. I tried removing the app, manually dropping the tables oc_ojsxc_presence and oc_ojsxc_stanzas in the database (I thought, they might be some unwanted relict from the app?) and reinstalling, no changes.

Any suggestions? Is it due to the internal server of the app, which is marked as experimental, did I misconfigured something or might there be a bud somewhere?

On executing the command, it gives the error “There are no commands defined in the “ojsxc” namespace.” Am I doing something wrong? I also do not find the folder lib/Command in the ojsxc-version you provided here…

Additionally, it might be nice, if this command is done automatically on installation of the app, because some people might run nextcloud without command line access.

This is probably because JSXC caches the roster in the localStorage and doesn’t asks for it every time you open a Nextcloud page.

@sualko is there a way in XMPP to inform a change of the roster, or to invalidate the cache? I think there are some ways in Nextcloud to be notified of new, changed and deleted users so then the server can send the new roster.
