I have created a taxonomy field programmatically and added to a custom content type which inherits from Document content type. In the document library when I chose "Edit properties" for an item (documemnt) the field is read only but when I open the document it is possible to change the field's value in DIP (not read only in DIP).
My field's name is status. I removed the built-in Status field and created a new on with same name but as Taxonomy Field. can it be the reason?
