[rules-users] Implementing multiple 'and' 'or' conditions

Hi, I've to write a rule in which there are multiple and, or conditions. Like ( MyEvent(prop = "1") or MyEvent(prop = "2") or MyEvent(prop = "3") ) and MyEvent(prop = "4") and MyEvent(prop = "5") I tried to implement it like $E: ( MyEvent(prop = "1") or MyEvent(prop = "2") or MyEvent(prop = "3") ) MyEvent(prop = "4") MyEvent(prop = "5") but it's throwing error expecting ')'. Can anyone please help me writting this rule? -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Implementing-multiple...
