We would like the file attachment field in an eForm to be hidden in subsequent tasks after initial upload task if no file has been uploaded for that field. If a file has been uploaded, then it should stay visible.
Is there a condition/attribute one could use? We would combine it with a task name condition (hidden if
!task.name = "xxx" && ???).
In the field validation tab of the upload control, check
hidden, then enter the code below:
this.CurrentWorkflowActionName !="INITIATES" && !REQUEST_ATTACHMENT.HasFile
REQUEST_ATTACHMENT with the full ID of your upload field, and replace
INITIATES with the action name where the file is uploaded.
