Symptoms
Issue with SCNull being saved when documents are uploaded
Diagnoses
Is there anyway to stop someone from saving an uploaded a document to the database when the document is not properly uploaded to the K2 form? I am getting a lot of SCNull documents in the database which I think is being caused by users clicking 'Add' multiple times on the form and only uploading one document.
Resolution
You can add condition in the rule to check whether the File Attachment control has value before letting the users create and item in SmartObject.
Please see attached Condition.png.
