Thanks a lot, Edson, for the quick reply yesterday. Here's another one. The following rule compiles, but Drools crashes upon insertion of an object. Same when calling a static method instead of a constructor. (Based on the Eclipse sample rule project) rule "rule1" when $p1:Message( message in ( (new String("A")), (new String("B")) ) ) then System.out.println("foo"); end java.lang.UnsupportedOperationException: does not support method call isAllowed(Object object, InternalWorkingMemory workingMemoiry) at org.drools.rule.ReturnValueRestriction.isAllowed( ReturnValueRestriction.java:177) at org.drools.rule.OrCompositeRestriction.isAllowed( OrCompositeRestriction.java:20) at org.drools.rule.MultiRestrictionFieldConstraint.isAllowed( MultiRestrictionFieldConstraint.java:70) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:132) at org.drools.reteoo.SingleObjectSinkAdapter.propagateAssertObject (SingleObjectSinkAdapter.java:22) at org.drools.reteoo.ObjectTypeNode.assertObject( ObjectTypeNode.java:153) at org.drools.reteoo.Rete.assertObject(Rete.java:177) at org.drools.reteoo.ReteooRuleBase.assertObject( ReteooRuleBase.java:192) at org.drools.reteoo.ReteooWorkingMemory.doInsert( ReteooWorkingMemory.java:71) at org.drools.common.AbstractWorkingMemory.insert( AbstractWorkingMemory.java:886) at org.drools.common.AbstractWorkingMemory.insert( AbstractWorkingMemory.java:858) at org.drools.common.AbstractWorkingMemory.insert( AbstractWorkingMemory.java:659) at com.sample.DroolsTest.main(DroolsTest.java:28) I'm on drools 4.0.2 and mvel14-1.2.8.
