I use a system of components that use the attachment field to supply identity documentation. I need to reset the dependent system of components in the event the user removes the attachment and provides a different one.
I've tried adding a change rule to the attachment field
It does not seem to trigger when the attached document is removed and a new one provided.
How do I detect when the user has changed the attached document?
The 'On Attachment Upload' rule can be used to detect attachment state change. This is a reliable indicator of when the document is uploaded to the server giving a true indication of the state of the system.
