Thanks for the response Since I dont actually need to keep a count of the number of strings that match the pattern in the list, I have changed your solution to the code below to make it simpler. rule "Matcher" when TestClass( $list : listOfStrings ) String( this matches "^a.b.*$" ) from $list then TestClass.setResponse( "Condition is True !!" ); end
However, when I run this I get the following error because it doesnt recognize the 'this' keyword [43,197]: unknown:43:197 Unexpected token 'this' Do you know what the problem could be ? -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/are-for-loops-possible-in-drools-tp1011729p1011787.html Sent from the Drools - User mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
