I just upgraded to Drools 4.0 and changed my assertObject calls to insert. I also switched from WorkingMemory to StatefulSession. The rules seem to be fine, but I am not able to retrieve any inserted objects from the working memory for some reason. Here is what I'm doing. I'd appreciate any suggestions... StatefulSession *workingMemory* = getActiveWorkingMemories(id); *workingMemory*.fireAllRules(); // Here is the rule that fires: * rule *"RecognizeBenefitsProgramEvent" * ** when* $edit: BenefitsProgramModelEdit() * then* * insert* (*new* *BenefitsProgramEvent*("BenefitsProgramEvent", $edit.getValidFrom(), "AnnualEnrollmentEvent")); * ** System*.out.println("Rule RecognizeBenefitsProgramEvent fired " ); * **end* I see the print statement in the console but the inserted object is not actually in the working memory. I look using this: Iterator events = *workingMemory*.iterateObjects(new ClassObjectFilter( BenefitsProgramEvent.class)); This iterator is empty. I also debug and look at the assetMap inside workingMemory and it never changes. Thanks, Michael

I found my problem, in case anyone else has this same issue (until 4.0.1which may have this fixed): The ClassObjectFilter's accept method works like this: public boolean accept(Object object) { return object.getClass().isAssignableFrom( this.clazz ); } which is opposite of what I expected. I want to find all the objects in working memory that implement a particular interface. So I created my own ObjectFilter that works like you'd expect: public boolean accept(Object object) { return this.clazz.isAssignableFrom(object.getClass()); } Hope it helps someone, Michael On 8/16/07, Michael Waluk <mwaluk(a)gmail.com&gt; wrote: > > The log file also shows that the BenefitsProgramEvent was inserted > properly.
