save fails with runtime exception instead of returning false

Reported by Gokul | August 29th, 2011 @ 04:24 PM

class Posting < Neo4j::Rails::Relationship
   before_validation :do_some_checks
   def do_some_checks
      puts "CHECK"

class Blog < Neo4j::Rails::Model

if for a post, the callback chain is halted (do_some_checks returns false), then
blog.save throws a runtime exception instead of returning false.

jruby-1.6.3 :007 > blog.save
RuntimeError: Can't save outgoing id: 2250 start_node: 8 end_node: 9
type:posts, validation errors ? #
