Warnings displayed by nodehierarchy_views

I get the following two errors when viewing some nodes:

Notice: Undefined property: stdClass::$nh_children_view in nodehierarchy_views_embed_children() (line 191 of modules/nodehierarchy/nodehierarchy_views/nodehierarchy_views.module).

Notice: Undefined index: nodehiararchy_children_embed in _element_info() (line 1373 of includes/form.inc).

Nothing seems to be broken as a result, but they were bothering me, so I fixed them. I think I've turned on stricter error reporting than the default.

I'll include the patch in the next post once I have the issue number.
