Re: Lua 5.2 creating globals with userdata

[Kevin Martin <kev82@...>]

First thought is that you haven't called luaopen_display_lib before createGlobal, so the metatable doesn't exist yet. Try the following assertion:

luaL_getmetatable(L, GEMINI_LINE_LUA_KEY);
assert(lua_type(L, -1) == LUA_TTABLE);
lua_setmetatable(L, -2);

Thanks,
Kev
