Issue in computing expressions

[garg-ketki]

public enum TestEnum {
    VALUE1,
    VALUE2
  }

List<TestObject> testList = new ArrayList();

class TestObject {
    private TestEnum testEnum;
    public TestEnum getTestEnum() {
        return testEnum;
   }
}

if (testList.get(0).getTestEnum() != null) {
      return testList.get(0).getTestEnum().ordinal(); // not working
}

TestEnum testEnum = testList.get(0).getTestEnum(); // worked
if (testEnum != null) {
      return testEnum.ordinal();
}

Library version: 0.4.4

The issue here is not enums, it's the expression testList.get(0).getTestEnum(). We don't track null checks on expressions that read out of lists. If you store testList.get(0) in a local things should work. I don't think we'll get to handling this use case anytime soon, but I'll leave it open just in case

@lazaroclapp #285 will fix this right?

[lazaroclapp]

Yes. This should be fixed now after #285 landed. We aren't cutting a release yet, I think, since that change + optional support by default should merit a 0.7.0 release. In the meantime, closing this issue. Feel free to re-open if not fixed on master or 0.7.0 when it is out.
