Hi All, When I'm trying to execute multiple evals I'm getting errors. Below is what I'm trying to do          MyEvent(prop1="XYZ") over window:time(1m) from entry-point MyStream               or             (MyEvent() over window:time(1m) from entry-point MyStream                and                Number($i1 : doubleValue)                from accumulate(                        MyEvent(                        prop1 == "CONNECT",                        prop2 == 3,                        eval((prop3 matches ("match "+getFirstNameRegex()+" Connect")) == true)                        ) over window:time(1m) from entry-point MyStream, count()                )                and                eval($i1 > getNodeCount()*0.35))        or                (MyEvent() over window:time(1m) from entry-point MyStream                and                Number($i2 : doubleValue)                from accumulate(                        MyEvent(                        prop1 matches "(second|Third{1}_CONNECT",                        prop2 == 1,                        eval((prop3 matches ("MatchOne|MatchTwo){1}::"+getMMSCNameRegex()+", failure")) == true)                        ) over window:time(1m) from entry-point MyStream, count()                )                and                eval($i2 > getConnectionCount()*0.4))        or                (MyEvent() over window:time(1m) from entry-point MyStream                and                Number($i3 : doubleValue)                from accumulate(                        MyEvent(                        prop1 matches "(E1|E2){1}_CONNECT",                        prop2 == 3,                        eval((prop3 matches ("REPT (one|five|seven){1}:: "+getServerID()+" is down")) == true)                        ) over window:time(1m) from entry-point MyStream, count()                )                and                eval($i3 > getThirdNodeCount()*0.5)) When I'm trying to execute the above LHS I get org.drools.rule.InvalidPatternException: Required Declarations not bound: '$i1'.
