Hi, I am trying to use the Guvnor rule editor to build rules. I created a fact model with a String field. But I can't figure out how to build a rule that this String field "not matches" a regex. I know DRL supports "not matches", but how to do it on the rule editor? Thanks in advance. -- View this message in context: http://drools.46999.n3.nabble.com/guvnor-rule-editor-tp4025672.html Sent from the Drools: User forum mailing list archive at Nabble.com.
