I tested with this instance and also 4.0.8 docker mode with Chrome, and variable prompting is working. Anything special at your side?

I have tested it with Firefox 84 and Chromium 87. Neither did work.
There are no JavaScript console errors and there is no Ajax request when typing @ into the editor field.

If you have any other ideas how to debug this please let me know.

It does not work on another OneDev instance using 4.0.7.

Please follow below steps to check if it works:

1. Login to code.onedev.io
2. Create a new project
3. Add file .onedev-buildspec.yml from web UI
4. Input @ in commands field

Please follow below steps to check if it works...

Well that is what I described in the issue description, isn't it? ;)

Also tested that with a brand new project; same issue here.

This is odd. I tested fine with different browsers and OS. Can you please help to debug this issue?

To debug it, please set up your dev environment following this: https://code.onedev.io/projects/onedev-manual/blob/4.0/pages/development-environment-setup.md

Then in browser, find file code-support.js and put a break point at line 26. Then input '@' to see why it is not being handled.

@mweimann any chance to look into source why this is not working at your side?

@robin thanks for asking. I may have some spare time at the week end and will check it then.

Found it: On my keyboard (DE layout) the @ sign does not have keyCode 50. Switching to key should solve this even for other layouts.
