Using index-event to call external function

[Marco Kögler <marco.koegler@...>]

Hi!

I've been tinkering a bit with Lua and C#. I'm trying to use the __index 
metatable event to re-route function calls to the C# side. My setup is 
like this:

On the Lua-Side I have a 'handle' to a C# object. This handle is in a 
table, which has a metatable attached to it. I use the metatable to 
intercept the index event. Here is some code, which evolved somewhat out 
of the ClassesWithMetatables article in the Wiki. It currently ignores a 
lot of stuff, but I want to get this simple thing working first before 
making everything 'nice':

function myIndex(t, func)
  return luaNET.call(t.handle, func);
end;

LuaNETObject = {};
LuaNETObject_mt = { __index = myIndex };

function LuaNETObject:new(handle)
  return setmetatable( {handle = handle}, LuaNETObject_mt);
end;

-- 1 is a valid handle
testObj = LuaNETObject:new(1);

-- should reroute the call
testObj:Hello();

OK, now the above code does call the C# function of the object in 
testObj correctly (it just prints something out), but after the last 
line Lua complains with this:

[string "function myIndex(t, func)   return luaNET...."]:1: attempt to 
call method `Hello' (a nil value)

Obviously, the table testObj did not contain a Hello-function. But, I 
thought if the index event handles this, then Lua would be silent. Can 
somebody help me out? Is there a clean way of achieving this? I hope my 
explanation is not too obscure. So, basically I would like to somehow 
signal Lua in the myIndex function that 'everything went alright'.

BTW, this is not related to Lua.NET ... I just couldn't find a better 
name for this, other than luaNET.

Thanks,
Marco
