This <UNCHANGED> stuff smells like a very bad codding pattern. Could not we use empty string and undef/NULL to handle empty values?

Hello Jonathan, I don't really see how to do that. If you create a course item this way: my $ci_id2 = ModCourseItem( itemnumber => $itemnumber, itype => '', ccode => 'BOOK', holdingbranch => '<UNCHANGED>', location => '<UNCHANGED>', ); or this way my $ci_id2 = ModCourseItem( itemnumber => $itemnumber, ccode => 'BOOK', holdingbranch => '<UNCHANGED>', location => '<UNCHANGED>', ); This results to the same when getting the course with GetCourseItem: itype is undef. Empty or null value are retrieved the same and we are unable to know if the value has changed or not. -- You are receiving this mail because: You are watching all bug changes.
