Building rule file that contains event declaration with @duration ends with NPE ------------------------------------------------------------------------------- Key: DROOLS-93 URL: https://issues.jboss.org/browse/DROOLS-93 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 6.0.0.Alpha1 Reporter: Petr Široký Assignee: Mario Fusco Attachments: drools93-reproducer.zip Building kbase with simple rule file with event declaration that has a @duration attribute ends with NPE. When the @duration is removed, file is built correctly. See attached maven reproducer (just run mvn test). The rule file looks like this: {code} package org.jboss.drools.example.kbase declare org.jboss.drools.example.kbase.SimpleFact @role(event) @duration(duration) end {code} Exception thrown when building the file: {code} java.lang.NullPointerException at org.drools.compiler.compiler.PackageBuilder.processTypeFields(PackageBuilder.java:2206) at org.drools.compiler.compiler.PackageBuilder.processTypeDeclarations(PackageBuilder.java:2123) at org.drools.compiler.compiler.PackageBuilder.mergePackage(PackageBuilder.java:1254) at org.drools.compiler.compiler.PackageBuilder.processTypeDeclarations(PackageBuilder.java:2000) at org.drools.compiler.compiler.CompositeKnowledgeBuilderImpl.buildTypeDeclarations(CompositeKnowledgeBuilderImpl.java:273) at org.drools.compiler.compiler.CompositeKnowledgeBuilderImpl.buildTypeDeclarations(CompositeKnowledgeBuilderImpl.java:249) at org.drools.compiler.compiler.CompositeKnowledgeBuilderImpl.buildPackages(CompositeKnowledgeBuilderImpl.java:87) at org.drools.compiler.compiler.CompositeKnowledgeBuilderImpl.build(CompositeKnowledgeBuilderImpl.java:76) at org.drools.compiler.kie.builder.impl.AbstractKieModule.buildKnowledgePackages(AbstractKieModule.java:140) at org.drools.compiler.kie.builder.impl.AbstractKieProject.verify(AbstractKieProject.java:39) at org.drools.compiler.kie.builder.impl.KieBuilderImpl.buildKieModule(KieBuilderImpl.java:207) at org.drools.compiler.kie.builder.impl.KieBuilderImpl.buildAll(KieBuilderImpl.java:160) at org.kie.internal.utils.KieHelper.build(KieHelper.java:25) {code}
