Hi!
The example has been updated accordingly:
http://github.com/neo4j-examples/java-astar-routing
Will keep track on when it breaks the next time :-)

It should use the factory methods in TraversalFactory instead.
How come we exposed DefaultExpander to begin with? Wasn't that class just
supposed to be an implementation detail?
The fact that it had the weird behavior of expanding all RelationshipTypes
when it was empty turns on the implementation detail warning light for me.
I'm working on refactoring the new traversal framework, so expect things to
change (and break) more. It's good that you report this though, since
examples should be updated to match the best practices. The new traversal
API is after all not stable yet (since 1.1 has not been released), but
I apologize for the inconvenience anyhow.
Cheers,
Tobias

Hi,
DefaultExpander.java was removed from the latest build
https://trac.neo4j.org/changeset/4590
How can i get the example from github working without the DefaultExpander ?
http://github.com/neo4j-examples/java-astar-routing
DefaultExpander relExpander = new DefaultExpander();
relExpander.add( RelationshipTypes.ROAD, Direction.BOTH );
AStar sp = new AStar( graphDb, relExpander, costEval, estimateEval );
Path path = sp.findSinglePath( NYC.getUnderlyingNode(),
SF.getUnderlyingNode() );
thanks
Paddy
