What went wrong, what did you observe?

I can't readd a contact via the share menu after i delete him.

Error while adding share

What did you expect, how polls should behave instead?

I should be able to add a contact again and via a public share a vote should be possible.

What steps does it need to replay this bug?

1. start a new poll

2. add user in sharing (maybe reload site afterwards)

3. delete this user (maybe reload site afterwards)

4. try to add this same user again -> Error while adding share

5. After deleting the users in the poll sharing

6. create a public link

7. try to use this public link to add user -> The Name foobar is invalid or reserved.

Additional Information

In the database polls_share there are:

id	poll_id	group_id	token	type	label	user_id	display_name	email_address	invitation_sent	reminder_sent	locked	misc_settings	deleted
40	5	0	kmXdNU4L	email		foobar@example.com	Foobar	foobar@example.com	0	0	0	NULL	1762761939
41	5	0	zfh4JUJU	email		foobar@example.com	Foobar	foobar@example.com	0	0	0	NULL	0

But i don't see the deleted entry somehow in the sharing menu (maybe i would be nice if i can readd exact this token again and don't generate a new one) and i also don't see the new entry - only a error message.

Can't approve this. After deleting a named share, I can effortless re-add it or use the name in a public registration.
In the first case the deletion mark is removed. In the second one a new user with the name of the deleted share is created.

Maybe its because this Nextcloud instance is running on webhosting by all-inkl.com with only webcron, no memcache and no PHP opache. I test this on a 2nd instance, same issue so i will add some screenshots.

add new share

delete this share

try to add share again

reload site

try to add share again bebause everything is empty

Did you execute ./occ polls:db:rebuild? Possibly a unique index is missing.

I am executing the same steps, but no error. What if you use another mail address (because your db seems to have two identical shares).

BTW: I have instances at all-inkl as well without this issue.

[Lky]

Okay, i will create a new instance in test this again with less apps.

polls:db:rebuild does not solve the issue.

If i reload the site after adding a share, the share menu will be empty, so no share shows up. There is no difference for custom share or a public one, both doesn't show up.

I still can't reproduce this. Do you have some log information from the console?

I think I did, what you did:

1. add an email share for test@foo.com (Token: Ftad5Sda)
2. delete the share right after it
3. revert the deletion (Token: Ftad5Sda)
4. delete again
5. add a new email share for test@foo.com (Token: MKzJpOGp)

All without any issue (Version is 8.5.0).

BTW: Reloading the page is not necessary, since the operation is a backend operation.

At least the registration problems you mention, but did not open a new issue for should be resolved, since I fixed some weird bugs regarding public shares.

What about your main issue. Does this still exist? I am still not able to reproduce it.
