p_id Null

[git2013vb]

Hi I tried the example but I noticed this code:

while node['p_id']:

I'm mistaken or because p_id is None he cant execute this?

_path.append(node)
node = path['nodes'][node['p_id']]

Thank you

If node['p_id'] returns None, then it will fail a "truthyness" test and therefore the while loop will stop.

Additionally, I am able to run the example without modifications made to it.
