In my local Sugar instance, I created a filter named "meeting_type_not_empty" in Meetings list view that searches for records where a given field is not empty. (Screenshot with the filter is attached.) Then I tried to find code that should have been automatically created when I added this filter by searching for the name of this filter in the code base. But the filter name was not found, even after I ran Quick Repair. How could the filter have been created without being added to the code base? Where would you expect the filter code to be created?
