To safely append a field to a NovaDB form, read existing attribute 5053 values first. Rebuild all CmsValue entries with incrementing sortReverse values so the new field is appended at the end, then send the complete replacement back via novadb_cms_update_objects.

Correct sortReverse ordering requires rebuilding all 5053 CmsValue entries with incrementing sortReverse values. This deterministic ordering ensures the newly appended attribute definition is placed at the end of the form's field list during the novadb_cms_update_objects replacement.

Updating a NovaDB form attribute replaces all existing fields because novadb_cms_update_objects expects a complete replacement of the 5053 CmsValue multi-value entries. To prevent data loss, you must read and reconstruct all current field definitions before appending the new attribute.

No, this process is designed to append a single new field to a form's field list without replacing other fields. It targets typeRef 50 objects and handles one attribute definition at a time to ensure correct read-modify-write ordering and prevent manual errors.

You need to use novadb_cms_get_object for form schema updates when performing a read-modify-write operation to append a field. It retrieves the existing 5053 attribute values from the typeRef 50 form object so you can reconstruct the full field list before updating.
