NPE when imports not available ------------------------------ Key: JBRULES-579 URL: http://jira.jboss.com/jira/browse/JBRULES-579 Project: JBoss Rules Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 3.1-m1 Reporter: Edson Tirelli Assigned To: Mark Proctor REPORTED BY DIRK BERGSTROM: ------------------------------------------------ Trying to compile this rule, I get an NPE: package foo; rule "Generates NPE" when $count : Thing( size > 0 ) from collect( Gizmo( length == 1 ) ) then System.out.println("boo"); end Like so: java.lang.NullPointerException at org.drools.rule.Rule.addDeclarations(Rule.java:316) at org.drools.rule.Rule.addPattern(Rule.java:304) at org.drools.semantics.java.RuleBuilder.build(RuleBuilder.java:320) at org.drools.semantics.java.RuleBuilder.build(RuleBuilder.java:215) at org.drools.compiler.PackageBuilder.addRule(PackageBuilder.java:366) at org.drools.compiler.PackageBuilder.addPackage(PackageBuilder.java:215) at org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java:181) at net.juniper.dash.DroolsTest.readRule(DroolsTest.java:106) at net.juniper.dash.DroolsTest.main(DroolsTest.java:22) This happens when there are two undefined classes referenced in a rule, with the second one inside a collect() statement. If I import Thing, or import Gizmo, or have a constraint on Gizmo not in a collect(), I get a parser exception, as expected.
