Identifiers disappearing on save
When we edit an object's metadata and save, the object identifier (idno) blanks out. Even if we replace the idno, it blanks out on save. In the database, the idno is also blank.
The same thing happens when editing a collection's metadata.
The object identifiers were populated with a batch-import of media, where the identifiers were set to be the filenames of the imported files. The collection identifiers were defined when creating each new collection.
Any idea what's going on here?
