<html><head><style type="text/css"><!-- DIV {margin:0px;} --></style></head><body><div style="font-family:times new roman, new york, times, serif;font-size:12pt"><DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>The following problem encountered:</DIV>
<DIV> </DIV>
<DIV>I have a rule defintion :</DIV>
<DIV> </DIV>
<DIV>----------------------------------------------dpd.drl</DIV>
<DIV>package ruletest;</DIV>
<DIV>import ruletest.IndividualNok;</DIV>
<DIV><BR>rule Female_NOK_sex_401<BR> //when (IndividualNok(nokRelationship==401) || IndividualNok(nokRelationship==402))<BR> when (IndividualNok(nokRelationship==401) || IndividualNok(nokRelationship==402) || IndividualNok(nokRelationship==403))<BR> then <BR> System.out.println("abc");<BR> end</DIV>
<DIV>------------------------------------------------</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV>When I tried the commented out LSH, it works, however, when i add one more expression to it , it fails with the following exceptions:</DIV>
<DIV> </DIV>
<DIV>Exception in thread "main" java.lang.NullPointerException<BR> at org.drools.base.extractors.BaseObjectClassFieldExtractor.getLongValue(BaseObjectClassFieldExtractor.java:103)<BR> at org.drools.base.ClassFieldExtractor.getLongValue(ClassFieldExtractor.java:144)<BR> at org.drools.reteoo.CompositeObjectSinkAdapter$HashKey.setValue(CompositeObjectSinkAdapter.java:467)<BR> at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:292)<BR> at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:183)<BR> at org.drools.reteoo.Rete.assertObject(Rete.java:121)<BR> at

<DIV>Any idea about this? is it a bug</DIV>
<DIV> </DIV>
<DIV>When I tried to create an additional rule with the 2 expression, it still fails. This error can be reproduced with the followng code:</DIV>
<DIV> </DIV>
<DIV>-------------------------the Main Class's main method</DIV>
<DIV> public static void main(String[] args) {<BR> // TODO code application logic here<BR> final PackageBuilder builder = new PackageBuilder();<BR> try {<BR> builder.addPackageFromDrl( new InputStreamReader( Main.class.getResourceAsStream( "dpd.drl" ) ) );<BR> } catch (DroolsParserException ex) {<BR> ex.printStackTrace();<BR> } catch (IOException ex) {<BR> ex.printStackTrace();<BR> }<BR>
<BR> final RuleBase ruleBase = RuleBaseFactory.newRuleBase();<BR> try {<BR> ruleBase.addPackage( builder.getPackage() );<BR> } catch (Exception ex) {<BR> ex.printStackTrace();<BR> }<BR> final StatefulSession session = ruleBase.newStatefulSession();<BR> IndividualNok individualNok = new IndividualNok();<BR> session.assertObject(individualNok);<BR> session.fireAllRules();<BR> session.dispose();<BR> }</DIV>
