i added a custom field to the doc “Items” named item_model. I also added a new doctype named Item Model. I have chosen “Link” as type and it links from “Item Model”. So far so good, now when i go to make a new item the field appears in the form. But when i klick the small edit-button there comes an error with “Not permitted”.
I have all rights, according to the admin. What can it be?
