[Koha-patches] [PATCH] Bug 7817 - Items Permanent location (shelving location) is set to NULL when item is edited

[David Cook]

From: Olli-Antti Kivilahti <olli-antti.kivilahti at jns.fi>

A quick fix to prevent more damages.
No perceived side-effects so far.

This is actually a perfectly good fix for this issue. I've changed
the explanatory comment to explain why.

Another option would be to remove the 'exists' check in the sub
_do_column_fixes_for_mod(), but this is just as functional.
