Rocket.chat: Adding users with mentions doesn't work inside of threads

[b90g]

Description:

When adding users to public channels via @user-mention it only works in the main Chat, not in a thread.

Steps to reproduce:

1. in a Public room
2. where user isnt in yet
3. in a Thread
4. mention someone @user

Expected behavior:

1. user would join the room.

Actual behavior:

1. user does not join the room.

Is this really the expected behavior ?
I'm generally not a fan of the whole mentions = invite idea.
Maybe I just want to mention someone so other people can easily click his username or just do it by habit.
IMHO are mentions and invites 2 seperate functions, but that's just me.

So you think the issue should be mentions add users to channels?....

Either way, please stream line this function so people don't assume falsely that when tagged in a thread, people are already in a room, because there is no user had joined the room-message.

I'm absolutely for a streamlined version, how do discussions in public rooms work? Can you invite people by mention there?
In my opinion there need to be some Checkboxes in Admin-> Messages.

[ X ] Mentions in public channels trigger invite
[ X ] Mentions in public discussions trigger invite
[ ] Mentions in private groups trigger invite
[ ] Mentions in direct messages trigger invite

But that would be a feature request.

Back to your described issue, I can only find this in the official documenation:

Joining new channels and starting direct messages
There are three ways of joining a public channel; through search, invites, or mentions.

So yes, the expected behaviour would probably be that mentions in public threads trigger an invite. At least there is no exception stated in the documentation that this won't work in threads.

It's just all in all not not really consistent imo.

Agree with you.
And maybe it could be servers side configurable settings (Does mention invites to public channel)

Totally agree! That would be nice!

I quite like Slack's approach to this. Give the option to the user.

I think we have some issues open for this, and it seems like it should be very easy to implement this system message instead #2194 . But is off topic for this bug :)
