Great article! Thank you. Unfortunately the event NWF.FormFiller.Events.RegisterRepeaterRowAdded is not triggered when I click on the add link in the attachment control. After adding a new row with the attachment id the event is not triggered altough it is a repeating control. My target is to save the form automatically after adding a document.
As far as I'm aware, you could easily track the Attachments being queued for an Attachments Control, by targeting the "click" event on the Add New Attachment link (or button).
However, for something so specific, I would recommend starting a new topic / thread so that you might get a little more exposure and help with any particular problems that you may encounter.
