Hi, All, I have a similar questions to Jame's question. I have a list of Strings which is wrapped in a class called Names, and what I want to get is to find all the elements that's equal to "targetStringname". How do I create a rule using guided rule editor in Guvnor to create a rule which looks like the following? (Our system requires users to be able to create their own rules and I doubt that the users will know how to write rules like the following). when $name: Names( ) $foundThese: ArrayList (size >0) from collect (String (this matches "targetname" ) from $name.names) then System.out.println("something happened here"); public class Names { private List <String> name = new ArrayList<String>(); } Thanks a bunch! ________________________________ From: "Nord, James" <JNord(a)nds.com&gt; To: rules-users(a)lists.jboss.org Sent: Tue, October 6, 2009 8:48:46 AM Subject: [rules-users] Guvnor test scenarios and collections. Hi all, One of our facts has a collection which the rules add to. I'm trying to write a test scenrio to cover the simple case where the fact with an empty collection runs through and ends up containing a value "default". However I can't work out how to get Guvnor to do this. I am presented with fact.blah and then "equals" or "does not equal" but no contains or does not contain. I have tried the MVEL syntax of [default] but this complains that the expectation fails as: "[myFact] field [myCollection] was [[DEFAULT]] expected [[DEFAULT]]." Is there any any way to do this?
