Re: [rules-users] Working Memory and agenda-group

One is SomeDefault and the other one is SomeDefaultX. The Declared type, as far as I remember overrides the to string with the representation that you are seeing there: SomeDefault( minValueA=100, minValueB=20.0, maxValueB=20000.0 ) What is SomeDefaultX??
