From 964f93e59f72b93191ed938d823af337b7d2c17e Mon Sep 17 00:00:00 2001 From: Ole Troan Date: Fri, 10 Jun 2016 13:22:36 +0200 Subject: Fix node siblings Siblings did not work at all. Fixed by generating sibling relationships earlier in vlib_node_main_init(). Also adding a node dynamically before nodes were initialised failed for sibling nodes.
