I have just made a project, on apex. I have added a master page to show me the detail of required entities, but in the master page (I even have added the primary key along with all the other attributes), but I cannot find the primary key for it. Then when I want to add any new raw to that table, it returns error because of leaving the attribute that is dedicated for the primary key empty.
Can anyone please find me a solution regarding building master pages issues in apex?
Please also find the pictures of the type of error I get in the link below
