Hi all,
I've tried drools 5.2 final version with much excitement but the default
create new drools project is already giving problems:
Issue 1. Exceptions when running default created .rf and .bpmn files.
When I ran ProcessTest.java with .rf file, I get:
java.lang.NullPointerException

When I ran ProcessTest.java with .bpmn file, I get:

My development environment is eclipse 3.6, drools plugin 5.2 final, java 6,
windows 7, jboss as 5.1 jdk 6.
Any help would be greatly appreciated.
