Compiler error on 5.2.0.CR1. Worked on 5.0.1 -------------------------------------------- Key: JBRULES-3061 URL: https://issues.jboss.org/browse/JBRULES-3061 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-compiler Affects Versions: 5.2.0.CR1 Environment: Java 5. Windows. Drools Master branch Reporter: Joe White Assignee: Mark Proctor The test below can be added directly to MiscTest in drools-compiler and run to reproduce the problem. The exception that occurs is pasted below the rule. If there is only one check in the Person object then the rule will compile, but adding in the part with "|| status != $inStatus" causes the exception. ######################TEST################################# @Test public void testMapVarCompare() { // String str = ""; str += "package org.drools\n"; str += "import org.drools.Person\n"; str += "import java.util.Map\n"; str += "import java.util.List\n"; str += "rule rule1 \n"; str += "when\n"; str += " $listOfMaps : List()\n"; str += " Map($inName : this['name'], $inStatus : this['STATUS']) from $listOfMaps\n"; str += " Person( name != $inName || status != $inStatus)\n"; str += "then\n"; str += "end\n"; try { KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add( ResourceFactory.newByteArrayResource( str.getBytes() ), ResourceType.DRL ); if ( kbuilder.hasErrors() ) { System.out.println(kbuilder.getErrors()); fail( "KnowledgeBuilder should not have errors" ); } } catch ( Exception e ) { e.printStackTrace(); fail( "Exception should not be thrown " ); } } ################################EXCEPTION################################################## Unable to build expression for 'inline-eval' : [Error: incompatible types in statement: class java.lang.Object (compared from: class java.lang.String)] [Near : {... name != $inName || status != $ ....}] ^ [Line: 1, Column: 1]'name != $inName || status != $inStatus' [Error: incompatible types in statement: class java.lang.Object (compared from: class java.lang.String)] [Near : {... name != $inName || status != $ ....}] ^ [Line: 1, Column: 1] : [Rule name='rule1'] [Error: incompatible types in statement: class java.lang.Object (compared from: class java.lang.String)] [Near : {... name != $inName || status != $ ....}] ^ [Line: 1, Column: 1] -- This message is automatically generated by JIRA.
