When I tried this, following exception was returned:
java.lang.NumberFormatException: For input string: ""
[ONetworkProtocolHttpDb]
Then, I got another message instead of the above when using OrientDB Studio:
java.lang.IllegalArgumentException: Cannot determine the graph element
type because the document class is null. Probably this is a projection, use
the EXPAND() function [ONetworkProtocolHttpDb]
and I use expand() instead of gremlin() only to return no record.
Note that in former case I used my demo app with OLD JavaScript
API<https://github.com/orientechnologies/orientdb/wiki/Javascript-API>,
and latter one I just used NEW OrientDB Studio.
I think I should use new orientdb-js
API<https://github.com/orientechnologies/orientdb-js>,
but assume APIs are not related to this problem...
2.
Because OrientDB returns exceptions when I send queries including gremlin
script but without FROM keyword, I add it for each query.
But now the number of resuts of the queries changes dependent on the target.
For example with a query select gremlin("g.v('9:9').out.id") from <target>,
when the target is V, the number of results is the number of elements in V,
and when the target is specific vertex(s) (whether it is used for the query
or not), like from [#9:9, #9:10, #9:1], the number of the results becomes
the number of selected vertex(s).
In addition, all results have the same value.
These things in 1 and 2 are also confirmed with 1.7rc2-SNAPSHOT.
Regards,
Shota
