Some slash-commands like /myroomnick not working in „pre-DM“

[weeman1337]

Steps to reproduce

1. Start a DM with someone, do not send the first message
2. Run a slash-command like /myroomnick

Other commands are also affected.

Outcome

What did you expect?

Some commands could be executed on room creation. For instance /myroomnick totally makes sense.

Others should not be available. Example for that would be /addwidget.

What happened instead?

Server error - unknown room

Will you send logs?

No

Kind of related at least for the other end: element-hq/element-meta#370

The issue is that no room exists yet for the command to be executed against. Element would need to locally cache it and when the first message gets sent, execute the cached commands first. Or merge them into the join event instead of sending additional rejoin events.

This is also related to per-space-profiles

This is about fixing the error for „pre-DM“ rooms. element-hq/element-meta#370 will remain valid.

@weeman1337 are we sure this will be considered fixed, a disabled command doesn't show up which might be a confusing UX, feeling broken and unclear as to why some rooms have the command and some others

[weeman1337]

Nope - not sure. But on the other hand in the current state some commands end up with „Server Error - Unknown room“.

@weeman1337 the PR is definitely an improvement, but a better designed solution may be desirable in the longer term. I do not think this issue will get closed by that PR, because /myroomnick will still not work in pre-DM, it just won't be an autocomplete suggestion either.

@t3chguy agree. Changed the PR not to close this issue.
