I want to make the attachment not required. I use these File upload and download process example (http://community.bonitasoft.com/project/file-upload-and-download-process...). I cannot submit the form when it is empty. How can I make it optional and can submit the form when it is null and have an attachment. If this cannot be done is there a workaround for attachment.
Note: I use the multiple attachment option since our user attach multiple of documents.
