0x80020011 Does not support a collection.

[mdauphin]

I just try luacom, and It's a great module!
But I have a problem to call C++ IDispatch property object.
My IDL interface :
interface IData : IDispatch
{..}
interface IDataDiff : IData
{
[propget, helpstring("Nombre")] HRESULT nbPoints([out, retval] ULONG* pVal);
...
};

My C++ code :
IData pData = InitializeDataDiff();
IDispatch pdisp = NULL;
pData->QueryInterface( IID_IDispatch, (void**)&pdisp );
luacom_IDispatch2LuaCOM(L, (void *) pdisp);
lua_setglobal(L, "data");

My LUA code:
value = data:nbPoints()
-- value = data.nbPoints -- return function !

I've COM HRESULT 0x80020011 Does not support a collection. I check in tLuaCom::call at line 340 the Invoke seem to be correct. My C++ COM code return S_OK, but in OLE microsoft code return x80020011.

Thanks !
