We have a custom entity that has a few dozen fields. When we open a bulk edit window for a Results list in Advanced Find, we are checking a single checkbox (to mark the record as completed). However, saving that one edit clears out several other - but not all! - of the fields in this custom entity.
It seems it is reading the bulk edit form to say "if the field is blank in the Bulk Edit form, clear that field on all records being edited."
Why is this happening? I am probably replacing this step with a Biz Process, but the behavior is unexpected and troubling so I want to know what is going on.
