Hi, I am unable to build packages using guvnor - Caused by: java.lang.NullPointerException at org.drools.compiler.PackageBuilder.validateUniqueRuleNames(PackageBuilder.java:826) at org.drools.compiler.PackageBuilder.addPackage(PackageBuilder.java:548) at org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java:287) Is there another method for creating deployable packages for loading by the RuleAgent? I'm using a Properties file stipulated directory (until Guvnor becomes a little more stable). Thanks
