Cory,

You can't modify the hierarchy during an active traversal - this will mess
up the traversal. You need to cache your updates and perform them between
traversals.

Subject: [osg-users] modify children in node callback?

In general, is it ok to modify child nodes in a node callback method?
That is, children of the node for which the callback was called?

I assume it must be. If not, how do you add or remove nodes of a scene
graph while running?
