I think this constant was removed in newer versions of wxWidgets and
therefore removed in wxLua.

Just create a variable ID_XYZABC = 12

If you don't care what ID a control is given you can use -1to have a
unique number set for you. However if you want to get back at the
control or be able to figure out which control an event came from you
should set a variable to some unique number, use it in the widget's
constructor, and then reference it as necessary.

Previously nil == 0 which now throws an error.
