Pattern with group by query bug

[pranjal0811]

I have the query like this - "from every e1=firewallStream[name == 'A']<3> -> e2=firewallStream [ name == 'B' ] within 40 seconds select 'AAAA' as ruleId group by e1[0].signatureId insert into outputstream"

when I execute it I got the error - e1 does not exist. The same query works well with the siddhi simulator.
