Mario Fusco commented on DROOLS-1318:
-------------------------------------

I added an enum Type to our Address test pojo and used it in a test case as it follows

{code}
    @Test
    public void testMvelWithEnum() {
        String drl =
                "import " + Address.class.getCanonicalName() + ";\n" +
                "rule R dialect \"mvel\" when\n" +
                "    $a : Address(type == Address.Type.OFFICE)\n" +
                "then\n" +
                "    $a.setType(Address.Type.HOME);\n" +
                "    update($a);\n" +
                "end";

        KieSession kieSession = new KieHelper().addContent(drl, ResourceType.DRL).build().newKieSession();

        Address address = new Address();
        address.setType( Address.Type.OFFICE );
        kieSession.insert( address );
        kieSession.fireAllRules();

        assertEquals(Address.Type.HOME, address.getType());
    }
{code}

As you can see I'm using the enum in both LHS and RHS and it works as expected.
