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

I did some debbuging with 'declare SomeDefault'. This is what I found: CASE1: RHS = drools.getWorkingMemory().insert(new SomeDefaultX()) Working memory objects: Object[fact 0:2:2082419441:2082419441:2:DEFAULT:com.sample.SomeDefaultX@7c1f32f1] Object[fact 0:1:140683595:140683595:1:DEFAULT:com.sample.ObjectA@862a94b] CASE2: RHS = insertDefault(drools.getWorkingMemory()) Working memory objects: Object[fact 0:2:176338845:1:2:DEFAULT:SomeDefault( minValueA=100, minValueB=20.0, maxValueB=20000.0 )] Object[fact 0:1:1125048577:1125048577:1:DEFAULT:com.sample.ObjectA@430ee101] Please note the difference between DEFAULT:com.sample.SomeDefault and DEFAULT:SomeDefault. So when inserting an object to WorkingMemory inside function insertDefault which is declared in DRL file something strange is going on... It seems like it is a bug. It is worth mentioning that I get following result inside insertDefault: System.out.println(SomeDefault.class.getName()); ---> com.sample.SomeDefault Hope it will help :) 2011/12/30 Maciej Gowin <maciej.abacus.gowin(a)gmail.com&gt; > > Of course it's only my guess.
