Symptoms

The user presented with the following error:

The Item references for this workflow could not be resolved because the View or instance of the view could not be found on the form.
 

Diagnoses

The user had created and Appified a List replete with Forms, SmartObjects and a WorkFlow. After designing and testing the WorkFlow the user then made alterations to their OOB New List Name] Form by deleting the List Name] Attachments List view and by extension the List Name] Add Attachments subview. After this alteration was made if the form were to be run it would submit and successfully update the list the associated workflow however would fail to initiate and would throw the error noted in 'Symptom.'
 

Resolution

The resolution in this case is to open and edit the form that was changed (by having its view removed) and dig into its rules section of the state that ISN'T the base state. There is an action connecting to the Save button rule that is responsible for initiating the workflow, open up that rule's edit page, find the Start WorkFlow action and open up its configuration from here WorkFlow FieldsandgtandgtandgtItem References. Here you will see two items. One of these items will be checked and have a companion SmartObject called "Form Name" the other will be vacant. Check the vacant one and type in "Form Name" Attachments. Save and finish the form. The workflow will now function properly.
