Matt Benson resolved JXPATH-113.
--------------------------------
Resolution: Fixed
Fix Version/s: 1.3
This one was obvious enough that just a claim of an NPE was good enough. I've
committed essentially the fix you've suggested, rev 617893. Thanks!
> NullPointerException in ChildContext
> ------------------------------------
>
> Key: JXPATH-113
> URL: https://issues.apache.org/jira/browse/JXPATH-113
> Project: Commons JXPath
> Issue Type: Bug
> Reporter: Michele Vivoda
> Priority: Minor
> Fix For: 1.3
>
>
> In ChildContext I get a NullPointerException, the error appears in method
> prepare()
> iterator = (startFromParentLocation ? parent.getParent() :
> parent).childIterator(nodeTest,
> reverse, startFromParentLocation ? parent : null);
>
> should be changed in my opinion to
> final NodePointer actualParent = startFromParentLocation ? parent.getParent()
> : parent;
> iterator = actualParent==null ? null :
> actualParent.childIterator(nodeTest,
> reverse, startFromParentLocation ? parent : null);
> The tests triggering the error are testIssue172_CountFollowingSiblingNode and
> testIssue172_CountPrecedingSiblingNode
