I have two People Picker fields on the edit form of my Sharepoint list (Approver and Requester). If I disable the fields, users are still able to remove the people that are already populated in the list.
The reason I'm disabling them is that I ran into a problem with expressions not evaluating if I have those fields hidden, since my expressions are depending on those fields. For instance, enable Approver Comments field only if Approver is the current user. If I hide the Approver field, that expression will not work.
Is there a way of either preventing users from removing people from a people picker field when the field is disabled, or using hidden fields in expressions?
Hope you can help.
