I have a person node. There are some internal fields only the admin can change (e.g. Internal person code). Some other fields users with certain roles can change (e.g. first name...).
I have built a custom page using panels for this; I added the desired fields for normal users to the panel and Then I added a selection rule to the variant, enabling the variant for the normal users.
When a normal user opens the form and saves it, the internal fields, which only should be edited by the admin are set to NULL, because they were not submitted of course.
Is there any setting I missed? I don't want to add all the internal fields.
