When you are checking out an issued item, we can see this confirmation: Item "Title (barcode)" is checked out to "Member (cardnumber)" Check in and check out? But after clicking "Yes" button, the item is just issued to current member, but is NOT checked in before! It looks like the all confirmations works the same way, but this one is special and need additional action (checking in the item).
(In reply to Josef Moravec from comment #0) > But after clicking "Yes" button, the item is just issued to current member, > but is NOT checked in before! Are you saying that the item remains checked out to both patrons, or that some action which is supposed to be performed upon check-in is not being performed? When I test it in master it works as I expect it to: The item is removed from the previous patron's account and checked out to the current one.
Yes, but now I tested it on master and on another 3.18.2 stable installation and everything went right, so It looks like there is something wrong with one concrete installation... I'll investigate it deeper...
I can't reproduce it now, so closing this bug.
