@DaanHoogland I agree that's the best practice though there is a glitch
here. Following code returns null if _cache is not null but element is null,
```java
T result = null
if (_cache != null) {
final Element element = _cache.get(id);
if (element != null) {
result = (T)element.getObjectValue();
}
} else {
result =findById(id, true, null);
}
return result;
```
