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
    public void testMapVarCompare() {
        //

        String str = "";
        str += "package org.drools\n";
        str += "import org.drools.Person\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";

            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 " );
        }
