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!

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?

Regards,

/James
