weird NPE

[Warner Onstine]

Hi all, I'm getting a weird NPE when saving a node, it doesn't appear
to be happening consistently.

I'm using M05 with spring data 2.1.0 (snapshot).

Any ideas?

That's a very poor error message, but it seems to be you trying to index a null value

Can you make sure that the index-name is correct ? No space on either end etc ?

Ah, shouldn't be, but I'll doublecheck, Thanks!

Warner, I also am seeing this same issue with my configuration upgrade to SDN 2.1.0.RC4 with neo4j 1.8.RC1 ... though reverting the SDN version back to 2.1.0.RC2 works fine (all domain tests pass)

Also tried just now to use SDN 2.1.0.RC3 and same thing as SDN 2.1.0.RC4 all repository tests fail even though under RC2 they passed locally.

Interesting, thanks for sharing. Doing some testing now so I'll look
into that to see if that may be the issue if my tests continue to fail
on non-null (empty) values.

It would be awesome if you could share a test-case that exhibits the behavior. So we can get it fixed for GA.

Mine did indeed come from null data trying to be inserted into the
graph db. Thanks for the help!
