Compiler absolutely correctly reports you that MyProperty can't use 
FMyField field because it is a class field in this case, not an instance 
field.

The next code will work again:

     TTest = class(TObject)
     private
       class var
         MyClassVar: Integer;
       var
         FMyField: string;
     published
       property MyProperty: string read FMyField write FMyField;
     end;
