E2124: Instance member '%s' inaccessible here (Delphi)

You are attempting to reference a instance member from within a class procedure.

program Produce;

  type
    Base = class
      Title : String;

      class procedure Init;
    end;

  class procedure Base.Init;
  begin
    Self.Title := 'Does not work';
    Title := 'Does not work';
  end;

begin
end.

Class procedures do not have an instance pointer, so they cannot access any methods or instance data of the class.

Copy Code

program Solve;

  type
    Base = class
      Title : String;

      class procedure Init;
    end;

  class procedure Base.Init;
  begin
  end;

begin
end.

The only solution to this error is to not access any member data or methods from within a class method.
