KnowledgeAgentImpl cannot build Resources with paramatereised ResourceConfiguration's
-------------------------------------------------------------------------------------

                 Key: JBRULES-2104
                 URL: https://jira.jboss.org/jira/browse/JBRULES-2104
             Project: JBoss Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-core
    Affects Versions: 5.0.1.FINAL
            Reporter: Graham Gear
            Assignee: Mark Proctor

The KnowledgeAgentImpl does not pass through ResourceConfiguration's through to KnowledgeBuilderImpl, making the building of configuration parametrised Resources not possible. Eg, trying to compile a DecisionTable (XLS) results in a NPE:

Caused by: 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:16)
	at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:508)
	at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:25)
	at org.drools.agent.impl.KnowledgeAgentImpl.rebuildResources(KnowledgeAgentImpl.java:385)
	at org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:119)
	at org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:108)
	at com.jboss.brms.poc.KnowledgeBaseManager.loadChangeSet(KnowledgeBaseManager.java:78)
	at com.jboss.brms.poc.test.rule.DecisionTableBRLClassPathRuleTest.<clinit>(DecisionTableBRLClassPathRuleTest.java:18)
	... 17 more

In general it would be good if the KnowledgeAgent would behave exactly as the KnowledgeBuilder under the same ChangeSet configuration.
