Dear all,
a crazy primitive question. How do I clear a graph (without doing rm -f) ?
If I delete all the nodes and relationships or use blueprints
graph.clear() I get a weird error later when adding new nodes:
Caused by: java.lang.IllegalStateException: First node[0] is deleted
and cannot be used to create a relationship

Also I'm using Spring Data Graph to create new nodes and relations.
Any ideas?
