I am currently using a number of forms in an Office 365 solution. Within the forms I frequently use controls that are connected to list columns. I have found that when I submit the form that the value gets deleted from the list column if the control is disabled. Am I getting this wrong, or should the field merely become read-only if it is disabled?
I also tried to keep the control enabled and set the Control Mode to 'display'. This also removed the value from the list column.
I only found this behaviour on O365 and not with my Forms 2013 instance.
