> In ChildContext I get a NullPointerException, the error appears in method prepare()
> {code:java}
> iterator = (startFromParentLocation ? parent.getParent() : parent).childIterator(nodeTest,
> reverse, startFromParentLocation ? parent : null);
> {code}
>
> should be changed in my opinion to
> {code:java}
> final NodePointer actualParent = startFromParentLocation ? parent.getParent() : parent;
> iterator = actualParent==null ? null : actualParent.childIterator(nodeTest,
> reverse, startFromParentLocation ? parent : null);
> {code}
> The tests triggering the error are testIssue172_CountFollowingSiblingNode and testIssue172_CountPrecedingSiblingNode
