No details in view student timetable dialog

[math]

After generating a timetable, I select Timetable -> Students -> Days horizontal.
In this dialog details of the selected activity are displayed on the righthand side.

However, when selecting "subgroups" mode, this is not working properly:
- Select "subgroups"
- Close the dialog
- Open the dialog again (so that it starts up in "subgroups" mode)
- Select an activity

Now the details section on the righthand side stays empty when selecting an activity.

Thank you for the bug report! You are a good finder, you found a way to replicate the bug. I saw it a long time ago, but could not always replicate and did not care too much.

I fixed it. Please get the latest snapshot from https://lalescu.ro/liviu/Backup-fet/ (for now). Please let me know as soon as possible if everything is OK now. I did more optimizations, so please test timetable view with selected Year, Groups, or Subgroups, detail the activity and make sure the details are OK, and lock/unlock. As I said, please let me know as soon as possible if everything is OK, since we are preparing these days a new release. I only changed the Students timetable view days horizontal, so you only need to test this.

I observed by reading the code that even locking did not work in this case (the snapshot fixed this, too).

Hi Liviu!

It's working now, thanks a lot. Also the locking-bug is solved in the current snapshot, as you already guessed. I was about to write another bug report.

Thanks a lot for your support!

Hello, math!

Thank you as well!

I changed only a bit (internally), maybe you can also test a bit the new snapshot: https://lalescu.ro/liviu/Backup-fet/ (only if your time permits).
