[fpc-pascal] Class helper properties

[Ryan Joseph]

http://wiki.freepascal.org/Helper_types#Usage says class helpers can use properties. Why am I getting this error?

program test;

type
	TMyObject = class
		m_num: integer;
		property num1: integer read m_num;
	end;
	THelper = class helper for TMyObject
		property num2: integer read m_num;	// ERROR: Unknown class field or method identifier "m_num"
	end;

begin
end.
