Student Id is said to be in the address book when it is not

[nus-pe-bot]

This issue seems to happen when blacklisting is involved.

I added one Sae Byeok with id/e1111112.

Then I blacklisted her from orientation camp.

Then I edited her id to become id/e1111114

Afterwards, when I tried editing her id back to e1111112, it gives this error that e1111112 already exists.

However there is no student with that id in the list. The full list I currently have is below.

This prevents me from adding certain ids after editing, especially if I added a student id wrongly at first.

Team's Response

Thank you for reporting this issue.

The problem here is occurring due to the way unique students are checked, and not due to an issue with blacklist.

However, the severity should be low instead of high as it is very unlikely and rare that a student ID would be edited to something different and then edited back to the same one consecutively (editing back and forth). This is because NUS Student Ids are unique and usually unchanging for every student in the first place, hence this is rare and is unlikely to affect normal operations of nustracker.
