[ https://issues.jboss.org/browse/JBRULES-3243?page=com.atlassian.jira.plug... ] Richard Ambridge updated JBRULES-3243: -------------------------------------- Description: If an item is declared @role (event) and the package name for that item is not the same as the package name of the rules, a Null pointer is thrown. was: If an item is declared @role (event) and the package name for that item is not the same as the package name of the rules, a Null pointer is thrown. Steps to Reproduce: Attached are some junit files Execute to receive: java.lang.NullPointerException at org.drools.reteoo.ReteooFactHandleFactory.newFactHandle(ReteooFactHandleFactory.java:56) at org.drools.common.AbstractFactHandleFactory.newFactHandle(AbstractFactHandleFactory.java:80) at org.drools.common.AbstractFactHandleFactory.newFactHandle(AbstractFactHandleFactory.java:65) at org.drools.common.NamedEntryPoint.createHandle(NamedEntryPoint.java:720) at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:280) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:882) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:841) at org.drools.impl.StatefulKnowledgeSessionImpl.insert(StatefulKnowledgeSessionImpl.java:255) Note, this only happens when PackageBuilder is used, the test will build one rule into a package and then load that package, create a stateful session and inject an object that is an Event If you move the Item.java into PackageA, this works. If you compile the rule inline using KnowledgeBuilder, this works. If the @role is removed, this works. was: Attached are some junit files Execute to receive: java.lang.NullPointerException at org.drools.reteoo.ReteooFactHandleFactory.newFactHandle(ReteooFactHandleFactory.java:56) at org.drools.common.AbstractFactHandleFactory.newFactHandle(AbstractFactHandleFactory.java:80) at org.drools.common.AbstractFactHandleFactory.newFactHandle(AbstractFactHandleFactory.java:65) at org.drools.common.NamedEntryPoint.createHandle(NamedEntryPoint.java:720) at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:280) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:882) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:841) at org.drools.impl.StatefulKnowledgeSessionImpl.insert(StatefulKnowledgeSessionImpl.java:255) -- This message is automatically generated by JIRA.

[ https://issues.jboss.org/browse/JBRULES-3243?page=com.atlassian.jira.plug... ] Edson Tirelli resolved JBRULES-3243. ------------------------------------ Fix Version/s: 5.3.0.Final Resolution: Won't Fix Richard, Thank you for reporting this. There are 2 parts to the problem reported here: 1. Your test case is wrong because it is only serializing one package, making your kbase inconsistent. Your test should serialize all packages and not only one of them: {code:title=snipped.java} //... Package[] pkgs = pkgBuilder.getPackages(); for( int i = 0; i < pkgs.length; i ++ ) { File pkgF = new File("/tmp/my.pkg"+i); FileOutputStream out = new FileOutputStream(pkgF); try { DroolsStreamUtils.streamOut(out, pkgs[i]); } finally { out.close(); } } //... for( int i = 0; i < pkgs.length; i ++ ) { File pkgFile = new File("/tmp/my.pkg"+i); builder.add(ResourceFactory.newFileResource(pkgFile), ResourceType.PKG); } //... {code} 2. The second part is Drools should be providing a proper error message for that, but at the moment Drools has no concept of dependency management. We plan to implement this in the future, and when that is done, then Drools will be able to detect that you are missing a package, but at the moment it is just impossible to do so. I will close this ticket and we will take care of part 2 when we add dependency management. -- This message is automatically generated by JIRA.
