decision table building => NPE ------------------------------ Key: JBRULES-3005 URL: https://issues.jboss.org/browse/JBRULES-3005 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-decisiontables Affects Versions: 5.2.0.M2 Reporter: Wolfgang Laun Assignee: Michael Anstis Fix For: 5.2.0.CR1 kBuilder.add( resource, resourceType.DTABLE ); results in a NPE: Exception in thread "main" java.lang.NullPointerException at org.drools.decisiontable.DecisionTableProviderImpl.compileStream(DecisionTableProviderImpl.java:26) at org.drools.decisiontable.DecisionTableProviderImpl.loadFromInputStream(DecisionTableProviderImpl.java:19) at org.drools.compiler.DecisionTableFactory.loadFromInputStream(DecisionTableFactory.java:18) at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:497) at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:28) at rss.drools.setup.Application.setup(Application.java:47) Notice that a simple DecisionTableConfiguration dtConf = KnowledgeBuilderFactory.newDecisionTableConfiguration(); kBuilder.add( resource, resourceType, dtConf ); is not sufficient, the DecisionTableConfiguration still needs a DecisionTableInputType Expected. there is a reasonable default DecisionTableConfiguration with DecisionTableInputType.XLS being set. The simple call worked fine in 5.1.
