[rules-users] WorkingMemoryListener & Declared Types

[Stephen Masters]

I just noticed your explanation of what you're trying to do. You might find these handy:

https://github.com/gratiartis/scattercode-drools-scenarios/blob/master/src/main/java/uk/co/scattercode/beans/BeanMatcher.java

https://github.com/gratiartis/scattercode-drools-scenarios/blob/master/src/main/java/uk/co/scattercode/beans/BeanPropertyFilter.java

https://github.com/gratiartis/scattercode-drools-scenarios/blob/master/src/main/java/uk/co/scattercode/drools/util/FactFinder.java

With those in place, I create JUnit assertions, which expect to find facts in working memory with particular properties.
