[luabind] dependency question

[Enno R. <en...@fu...>]

I've written a simple class that has a string member which I want to be 
accessible as a readonly property. Do I have to specify a dependency policy, 
or is it enough to write .property("name", &Region::getName) ?

Because in the example below, when I add dependency(result, self), I get the 
following message from VC7:

c:\libraries\luabind\luabind\detail\property.hpp(83) : error C2784: 'int 
luabind::detail::set(void (__cdecl *)(T &,A1),T *,lua_State *,Policies *)' : 
could not deduce template argument for 'void (__cdecl *)( &,<template 
parameter>)' from 'luabind::detail::policy_cons<H,T>'

Enno.

Sample code:
class Region {
public:
   Region(const std::string& name) : m_name(name) {}
   const std::string& getName(void) const { return m_name; }

private:
   std::string m_name;
};

class_<Region>(L, "region")
   .def(constructor<const std::string&>())
   .property("name", &Region::getName, dependency(result, self))
   ;
