Re: Wrong userdata pointer returned since update to luabind 0.9

Here are the two functions...

bool CLuaDialog::Create(const char* Name,
luabind::table<luabind::object> const& Rect) {
	CRect r;

	if(luabind::type(Rect) == LUA_TTABLE) {
		r.SetRect(luabind::object_cast<int>(Rect[1]),
luabind::object_cast<int>(Rect[2]),
luabind::object_cast<int>(Rect[3]),
luabind::object_cast<int>(Rect[4]));
	}

	CString strWndClass=AfxRegisterWndClass(0,
AfxGetApp()->LoadStandardCursor(IDC_ARROW),GetSysColorBrush(COLOR_WINDOW),NULL);
	bool re = !!CLuaWnd<CWnd>::CreateEx(WS_EX_CLIENTEDGE, strWndClass,
UTF8ToUnicode(Name).c_str(), WS_POPUP | WS_CAPTION, r,
AfxGetMainWnd(), 0);
	ASSERT(re);

	SetFont( CFont::FromHandle(
		(HFONT)::GetStockObject(DEFAULT_GUI_FONT)
		) );

	HICON hIcon = ::LoadIcon(AfxGetInstanceHandle(),
MAKEINTRESOURCE(IDR_MAINFRAME));
	CWnd::SetIcon(hIcon, FALSE);

	return re;
}

bool CLuaLabel::Create(luabind::object const& ParentWindow,
luabind::table<luabind::object> const& Rect) {
	CRect r;
	CLuaWnd<>* pParent = NULL;

	if(luabind::type(ParentWindow) == LUA_TUSERDATA) {
		pParent = luabind::touserdata<CLuaWnd<>>(ParentWindow);
	}

	if(luabind::type(Rect) == LUA_TTABLE) {
		r.SetRect(luabind::object_cast<int>(Rect[1]),
luabind::object_cast<int>(Rect[2]),
luabind::object_cast<int>(Rect[3]),
luabind::object_cast<int>(Rect[4]));
	}

	ASSERT(pParent->IsWindowVisible());
	bool re = !!CExtLabel::Create(L"Label", WS_CHILD | WS_VISIBLE |
SS_CENTERIMAGE | SS_NOTIFY /*| WS_TABSTOP | WS_BORDER | ES_AUTOHSCROLL
| ES_LEFT*/, r, pParent, 1);
	ASSERT(re);

	SetFont( CFont::FromHandle(
		(HFONT)::GetStockObject(DEFAULT_GUI_FONT)
		) );

	return re;
}

The code has worked before i switched to luabind 0.9, but perhaps you
has an idea what the problem is...

http://clip2net.com/clip/m7085/1267019396-clip-2kb.png here you can
see the pointer of the dialog object
http://clip2net.com/clip/m7085/1267019455-clip-4kb.png and here one
lua line after (the lualabel call) with a different pointer of dialog
object
