This is a bit dirty, cn_sort is not passed from the UI but built in
Koha::Item->store depending on the values of itemcallnumber and
cn_source.
It must be updated only if one of those 2 attributes are modified.
The problem is that, as it's not passed, $item->{cn_sort} does not exist,
and set_or_blank will set it to undef.
The trick here is to backup the value before set_or_blank and set it
back to the item object.
Another solution would be to force the processing of cn_sort each time
we call Koha::Item->store. I don't think that's a good idea.
Test plan:
- Create a new item with a cn_source value and an itemcallnumber value
- write a quick report to see the cn_sort value: SELECT cn_sort FROM items WHERE itemnumber=your itemnumber, see your item has a cn_sort value
- edit your item and save it without changing either the cn_source of the itemcallnumber
- run your report again, cn_sort is not modified
- edit your item, changing either the cn_source or itemcallnumber
- run report again, cn_sort is modified as expected
