You are right, of course. Thanks for pointing it out.
I absentmindedly copied the sequence from the result of an early script where the nodes were in that order. Using the same structure that we have in the company example, the post-order traversal is correct. Just change "callback" into "callbackback" and the printout will be:
net empl: 6 budget: 25000 str empl: 8 budget: 65000 sales empl: 14 budget: 90000 pers empl: 4 budget: 10000 res empl: 10 budget: 100000 dev empl: 15 budget: 90000 R&D empl: 25 budget: 190000 company empl: 43 budget: 290000 | <company> /--------+---------\ | | | <sales> <pers> <R&D> /-----\ /-----\ | | | | <net> <str> <res> <dev>
