[luabind] Creating instances by C++ of a class defined in lua

[Christian <zap...@gm...>]

Hello!

I have defined a class in lua like this one:

---------------------------------------------
class 'luaclass'

function luaclass:__init()
         self.val = 0;
end

function luaclass:setVal(num)
         self.val = num;
end

function luaclass:e()
         print(self.val);
end
---------------------------------------------

I want to create instances of "luaclass" by C++. I have tried it this way, 
which doesn't give any error but calls to memberfunctions of "luaclass" 
dont work correctly. If I do something like the following it looks like 
only one instance was created.

---------------------------------------------
luabind::object my_class(luabind::get_globals(L_)["luaclass"]);
luabind::object my_class2(luabind::get_globals(L_)["luaclass"]);

luabind::call_member<void>(my_class, "setVal", 10);
luabind::call_member<void>(my_class2, "setVal", 20);

luabind::call_member<void>(my_class, "e");
luabind::call_member<void>(my_class2, "e");

luabind::call_member<void>(my_class, "setVal", 11);
luabind::call_member<void>(my_class2, "setVal", 22);

luabind::call_member<void>(my_class, "e");
luabind::call_member<void>(my_class2, "e");
---------------------------------------------

I expected (hoped) to get this:

10
20
11
22

... but got this:

20
20
22
22

I would be very thankful for any advice how to do this in the right way.

Greetings,
Christian
