Re: Destructor problems with tolua 4.0

[Jardar Johannes Maatje <maatje@...>]

I tested a bit more and I will always get (null) as the value of the data
stored at the key, 'valuetype'. Why is not this value the same as the
'tag' variable that I set earlier on?

 toluaI_getregistry(L,"tolua_tbl_clone");
 lua_pushuserdata(L,value);
 lua_pushnumber(L,tag);
 lua_settable(L,-3);
 lua_pop(L,1);

	char buffer[10000] = "Start :\n";
	toluaI_getregistry(L,"tolua_tbl_clone");
	lua_pushnil(L);
	while (lua_next(L, -2) != 0) {
		char *keytype = lua_typename(L, lua_type(L, -2));
		char *valuetype = lua_typename(L, lua_type(L, -1));
		lua_pop(L, 1);
	}
