sql - Duplicated edges with the same @rid in OrientDB -

-

i've discovered strange behaviour when querying edge class using orientdb (community-2.1-rc5). database returning exact same edge exact same @rid , exact same data, twice. instinct says bug...

this query

select e @class='likes' , (out in [#12:0,#12:221]) , in=#36:1913

and orientdb studio returns

this makes no sense. if go vertex , query likes relationship returns 1 registry... faced problem this?

this database i'm using if helps

to bug, should make request join google group. stackoverflow not best place kind of bug.

the problem somehow duplicated edge mistake. orientdb let unknown reason.

here bug discussion on orientdb google group : https://groups.google.com/forum/#!topic/orient-database/car7yujczci

in discussion luca(creator of orientdb) says : 

"the problem without transaction creation of edge dirty. orientdb tries fix dirty reference, maybe that's  reason why next time exception raised. i've changed    default behavior of sql commands against graphs  transactional"

upgrading recent version of orientdb ideal. maybe bug has been fixed.
