Hello,
Newbie question: I got an exception for this code:
public final String getNotes () {
if (underlyingNode != null)
return (String) underlyingNode.getProperty(Constants.PERSON_NOTES, null);
else
return null;
}
I would expect this code can handle the retrieving of the Notes property
correctly, whether there is a such property or not. But this is the exception I
saw:
---------
Exception in thread "AWT-EventQueue-0"

This is how I retrieve the Person node:
public Person getPersonByName (String name) {
Person person = null;
if (name != null && name.length()>0) {
Transaction tx = graphDb.beginTx();
try {
IndexHits<Node> hits = indexService.getNodes(Constants.NODE_TYPE,
Constants.PERSON_NODE);
if (hits != null && hits.size()>0) {
for (Node hit : hits) {
if (((String)hit.getProperty(Constants.PERSON_NAME)).equals(name)) {
person = new Person (hit);
break;
}
}
}
} finally {
tx.finish();
}
}
return person;
}
---------------
Anything wrong ?
Appreciate any advice!
rgds,
canal
