[SFC-181] NullPointerException when creating RSP without any topology node connected

Tue, 13 Dec 2016 14:02:55 +0000

NullPointerException when creating a RSP and not a single topology node is connected. Stack trace shows that the source is an unchecked iteration on the topology nodes list.

The problem can be reproduced with rest-sender.py standard SFC REST provisioning while no dp nodes are connected.
