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-compiler (expert)
Affects Versions: 5.2.0.M2
Reporter: Wolfgang Laun
Assignee: Mark Proctor
kBuilder.add( resource, resourceType.DTABLE ); results in a NPE:
Exception in thread "main" java.lang.NullPointerException

org.drools.decisiontable.DecisionTableProviderImpl.compileStream(DecisionTableProviderImpl.java:26)

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.
