NullPointerException when querying out vertices

[ylopotun]

When we perform the following query (e.g. via console):
select expand(out('record')) from 14:15 limit 30
it returns an exception:
Error: com.orientechnologies.orient.core.exception.OCommandExecutionException: Error on execution of command: sql.select expand(out('record')) from 14:15 limit 50
Error: java.lang.NullPointerException

I'll send our sample DB via e-mail.

Applied a general high level fix that avoids the problem (on graph API).
Keeping this open to investigate possible flaws in RidBag iterators at a lower level

@Laa any advice is welcome on this

Thanks Luigi. Will your fix work for an existing data or only for the newly created data?

Hi Yuriy,

the fix will work also on existing data. I tried it on your db and it
worked fine.

Thanks

Luigi

So, the mentioned exception no longer appears, but if I do:
select from [14:93, 14:94]

I get another NullPointerException in the server log:

mmm.. let me check...

[luigidellaquila]

Ok, I reproduced the problem.
It's another issue, different from the first one, we are on it
