I encountered the same problem after updated from 2.0.3 to 2.0.5, if you update studio page, then connection is reestablished correctly, so after every gremlin query need press f5. Database is not closed probably, merely studio connection drops. I think it's a new bug, have to make an issue on github.
About creating a variable - there is no way to. Just use Rexster or gremlin console app(inside orientdb is one). -- --- You received this message because you are subscribed to the Google Groups "OrientDB" group.
