Ok, this one works. But my error was another one. I use tolua++ as interface to LUA. But it has not all features I need. So I tried to get my data "through" tolua++. But it seems tolua++ hits me here. If I go into the generated binder code and change "return 0;" to "return 1;" it works. If I use "return 1;" to set the number of results before tolua++ gets the function tolua++ push the "1" onto the stack. But this isn't what I like. :-(

Do you understand the problem?

I'm reading this document. Very good!
