Re: [rules-users] "unable to resolve token" in simple mvel RHS

Hi, with Drools 4.0.4 and MVEL 1.4, simple RHS like this one fail for me: --- package test; dialect "mvel" rule "Rule #1" when then System.out.println("now computing 1+1..."); Integer two = new Integer(2); System.out.println(two); end --- now computing 1+1... org.mvel.CompileException: unable to resolve property: two at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.compileGetChain( ReflectiveAccessorOptimizer.java:288) at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.optimizeAccessor (ReflectiveAccessorOptimizer.java:109) at org.mvel.ast.ContextDeepPropertyNode.getReducedValueAccelerated (ContextDeepPropertyNode.java:26) at org.mvel.ast.PropertyASTNode.initializePropertyNode( PropertyASTNode.java:123) at org.mvel.ast.PropertyASTNode.getReducedValueAccelerated( PropertyASTNode.java:26) at org.mvel.ExecutableAccessor.getValue(ExecutableAccessor.java :45) at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.getMethod( ReflectiveAccessorOptimizer.java:521) at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.compileGetChain( ReflectiveAccessorOptimizer.java:260) at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.optimizeAccessor (ReflectiveAccessorOptimizer.java:109) at org.mvel.ast.LiteralDeepPropertyNode.getReducedValueAccelerated (LiteralDeepPropertyNode.java:28) at org.mvel.MVELRuntime.execute(MVELRuntime.java:88) at org.mvel.CompiledExpression.getValue(CompiledExpression.java :111) at org.mvel.MVEL.executeExpression(MVEL.java:235) at org.drools.base.mvel.MVELConsequence.evaluate( MVELConsequence.java:47) at org.drools.common.DefaultAgenda.fireActivation( DefaultAgenda.java:550) at org.drools.common.DefaultAgenda.fireNextItem(DefaultAgenda.java :514) at org.drools.common.AbstractWorkingMemory.fireAllRules( AbstractWorkingMemory.java:471) at org.drools.common.AbstractWorkingMemory.fireAllRules( AbstractWorkingMemory.java:433) at org.libx.autodetect.DroolsDriver$Host.fireAllRules( DroolsDriver.java:63) at org.libx.autodetect.DroolsDriver.main(DroolsDriver.java:136) Caused by: org.mvel.PropertyAccessException: unable to resolve property: two at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.getBeanProperty( ReflectiveAccessorOptimizer.java:382) at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.compileGetChain( ReflectiveAccessorOptimizer.java:257) ... 19 more org.mvel.CompileException: unable to resolve token: two at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.compileGetChain( ReflectiveAccessorOptimizer.java:297) at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.optimizeAccessor (ReflectiveAccessorOptimizer.java:109) at org.mvel.ast.LiteralDeepPropertyNode.getReducedValueAccelerated (LiteralDeepPropertyNode.java:28) at org.mvel.MVELRuntime.execute(MVELRuntime.java:88) at org.mvel.CompiledExpression.getValue(CompiledExpression.java :111) at org.mvel.MVEL.executeExpression(MVEL.java:235) at org.drools.base.mvel.MVELConsequence.evaluate( MVELConsequence.java:47) at org.drools.common.DefaultAgenda.fireActivation( DefaultAgenda.java:550) at org.drools.common.DefaultAgenda.fireNextItem(DefaultAgenda.java :514) at org.drools.common.AbstractWorkingMemory.fireAllRules( AbstractWorkingMemory.java:471) at org.drools.common.AbstractWorkingMemory.fireAllRules( AbstractWorkingMemory.java:433) at org.libx.autodetect.DroolsDriver$Host.fireAllRules( DroolsDriver.java:63) at org.libx.autodetect.DroolsDriver.main(DroolsDriver.java:136) Caused by: org.mvel.UnresolveablePropertyException: unable to resolve token: two at org.mvel.ast.PropertyASTNode.initializePropertyNode( PropertyASTNode.java:127) at org.mvel.ast.PropertyASTNode.getReducedValueAccelerated( PropertyASTNode.java:26) at org.mvel.ExecutableAccessor.getValue(ExecutableAccessor.java :45) at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.getMethod( ReflectiveAccessorOptimizer.java:521) at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.compileGetChain( ReflectiveAccessorOptimizer.java:260) ... 12 more Caused by: org.mvel.CompileException: unable to resolve property: two at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.compileGetChain( ReflectiveAccessorOptimizer.java:288) at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.optimizeAccessor (ReflectiveAccessorOptimizer.java:109) at org.mvel.ast.ContextDeepPropertyNode.getReducedValueAccelerated (ContextDeepPropertyNode.java:26) at org.mvel.ast.PropertyASTNode.initializePropertyNode( PropertyASTNode.java:123) ... 16 more Caused by: org.mvel.PropertyAccessException: unable to resolve property: two at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.getBeanProperty( ReflectiveAccessorOptimizer.java:382) at org.mvel.optimizers.impl.refl.ReflectiveAccessorOptimizer.compileGetChain( ReflectiveAccessorOptimizer.java:257) ... 19 more etc. It appears to be related to the use of MVEL - the same rule with 'dialect "java"' executes correctly. - Godmar _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
