I've got a requirement where I need to set conditional validation against the Attachment control.
I was hoping I could figure out a way of doing this using rules, but I'm not able to investigate as I found the following issue. When I try to name the attachment control in the designer, it doesn't save the name, therefore it cannot be access through the "Named Controls" tab.
I'm not certain that rules will achieve want I require as it is, but it seems like a bug that you cannot name an attachment control.
a) confirm the same issue for me of not being able to name the control
b) think of a way to achieve what I need in the responsive designer
The form is already live and this is a new requirement so switching to classic designer is not really an option now.
