Re: [rules-users] 5.3.0.Final throws RuntimeDroolsException: Unable to merge resource attribute for type declaration

I was able to work around this problem by filtering out the KnowledgePackage containing my NormalizedEvent. In Drools 5.2.0 there was no problem adding this KnowledgePackage multiple times but apparently 5.3.0 doesn't cope with it well. I'm still not sure if that is a feature or a defect in 5.3.0. In any event doing the following make the exception go away. I'm still curious if this is a feature or a defect in 5.3.0. Any thoughts or opinions regarding are welcome. String globals = readDrlfile("globals.drl"); String newRules = readDrlfile("rulesToAdd.drl"); knowledgeBuilder.add(ResourceFactory.newReaderResource(new StringReader(globals + newRules))); if (knowledgeBuilder.hasErrors()) { throw exception ... } // No exception so compile succeeded --- BTW, it's using JANINO Collection<KnowledgePackage> pkgs = knowledgeBuilder.getKnowledgePackages(); pkgs=filterOutAnyPackageThatHasNoRulesAndNameMatchingNormalizeEventPackageName(pkgs); knowledgeBase.addKnowledgePackages(pkgs); // NO ERROR ANYMORE -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-5-3-0-Final-throws-RuntimeD...
