Existing code continues to add views with the same id. You need to make id of new views unique, or change the code, so it will add only one tab for one line in the list

i see your code line 44, but press 1 to 2 to 1 to 2 to 1 to 2 (quickly), the tabview crazy switch in 1 to 2\2 to 1 still,
can you try again

Yep, it is a bit more stable, but still behave incorrectly.

We will investigate and will fix the issue.

that’s right, best wish for you
