[rules-users] Problem with rule when loaded as PKG

[Markus Undhagen]

Hi
I have have a file with some rules. When I load the rules as a drl-file all my junit-tests work. But when I load the rules as PKG one of the rule is failing. 
This is the rule causing the problem
rule "Lookup synonym"    when    	$normalization : NormalizationFact(valid, resultFact == null)    	NormalizerMetadataService(synonymNames contains $normalization.type )        $synonymService : SynonymService()    then    	System.out.println(drools.getRule().getName());    	modify($normalization) {    		setResultFact(new ResultFact($synonymService.getValue($normalization.getType(), $normalization.getValue())))    	}end
After some investigation I can reduce the problem to 
setResultFact(new ResultFact(""))   <-------------------------  WorkingsetResultFact(new ResultFact(null)) <------------------------- Not working, see log below
This is the code executed in ResultFact
public class ResultFact {	private final String result;	private final boolean valid;
	public ResultFact(String result) {		this(result, true);	}
	public ResultFact(String result, Boolean valid) {		super();		this.result = result;		this.valid = valid;	}
        other methods ...}
The exception I get is 
Exception executing consequence for rule "Lookup synonym" in normalization: [Error: $normalization.setResultFact(new ResultFact(null)): array index out of bounds.][Near : {... $normalization.setResultFact(n ....}]             ^[Line: 1, Column: 1]	at org.drools.runtime.rule.impl.DefaultConsequenceExceptionHandler.handleException(DefaultConsequenceExceptionHandler.java:39)	at org.drools.common.DefaultAgenda.fireActivation(DefaultAgenda.java:1297)	at org.drools.common.DefaultAgenda.fireNextItem(DefaultAgenda.java:1221)	at org.drools.common.DefaultAgenda.fireAllRules(DefaultAgenda.java:1456)	at org.drools.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:710)	at org.drools.common.AbstractWorkingMemory.fireAllRules(AbstractWorkingMemory.java:674)	at org.drools.impl.StatefulKnowledgeSessionImpl.fireAllRules(StatefulKnowledgeSessionImpl.java:230)	at com.mawell.normalize.service.rule.DroolsRuleEvaluatorImpl.evaluate(DroolsRuleEvaluatorImpl.java:62)	at com.mawell.normalize.service.infrastructure.util.backend.SynonymServiceTest.execute(SynonymServiceTest.java:126)	at com.mawell.normalize.service.infrastructure.util.backend.SynonymServiceTest.execute(SynonymServiceTest.java:115)	at com.mawell.normalize.service.infrastructure.util.backend.SynonymServiceTest.ShouldNotTranslate_q(SynonymServiceTest.java:75)	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)	at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)	at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)	at java.lang.reflect.Method.invoke(Method.java:597)	at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44)	at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15)	at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41)	at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20)	at org.junit.runners.BlockJUnit4ClassRunner.runNotIgnored(BlockJUnit4ClassRunner.java:79)	at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:71)	at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:49)	at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193)	at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52)	at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191)	at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42)	at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184)	at org.junit.runners.ParentRunner.run(ParentRunner.java:236)	at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50)	at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38)	at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467)	at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683)	at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390)	at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)Caused by: [Error: $normalization.setResultFact(new ResultFact(null)): array index out of bounds.][Near : {... $normalization.setResultFact(n ....}]             ^[Line: 1, Column: 1]	at org.mvel2.optimizers.impl.refl.ReflectiveAccessorOptimizer.compileGetChain(ReflectiveAccessorOptimizer.java:424)	at org.mvel2.optimizers.impl.refl.ReflectiveAccessorOptimizer.optimizeAccessor(ReflectiveAccessorOptimizer.java:143)	at org.mvel2.ast.ASTNode.optimize(ASTNode.java:159)	at org.mvel2.ast.ASTNode.getReducedValueAccelerated(ASTNode.java:115)	at org.mvel2.compiler.ExecutableAccessor.getValue(ExecutableAccessor.java:42)	at org.mvel2.ast.WithNode$ParmValuePair.eval(WithNode.java:278)	at org.mvel2.ast.WithNode.getReducedValueAccelerated(WithNode.java:67)	at org.mvel2.ast.InterceptorWrapper.getReducedValueAccelerated(InterceptorWrapper.java:40)	at org.mvel2.MVELRuntime.execute(MVELRuntime.java:85)	at org.mvel2.compiler.CompiledExpression.getDirectValue(CompiledExpression.java:123)	at org.mvel2.compiler.CompiledExpression.getValue(CompiledExpression.java:119)	at org.mvel2.compiler.CompiledExpression.getValue(CompiledExpression.java:113)	at org.mvel2.MVEL.executeExpression(MVEL.java:930)	at org.drools.base.mvel.MVELConsequence.evaluate(MVELConsequence.java:104)	at org.drools.common.DefaultAgenda.fireActivation(DefaultAgenda.java:1287)	... 32 moreCaused by: java.lang.StringIndexOutOfBoundsException: String index out of range: -1	at java.lang.String.substring(String.java:1931)	at java.lang.String.substring(String.java:1904)	at org.mvel2.util.ErrorUtil.rewriteIfNeeded(ErrorUtil.java:12)	at org.mvel2.optimizers.impl.refl.ReflectiveAccessorOptimizer.getMethod(ReflectiveAccessorOptimizer.java:959)	at org.mvel2.optimizers.impl.refl.ReflectiveAccessorOptimizer.compileGetChain(ReflectiveAccessorOptimizer.java:377)	... 46 more
