getPointer() returns not null

[Psi Aushilfe3 <Au...@prosieben.de>]

Hi!

JXPathContext.getPointer(), javadoc: "Traverses the xpath and returns a
Pointer. A Pointer provides easy access to a property. If the xpath
matches no properties in the graph, the pointer will be null."

Well, this seem not to (always?) be true. I have to check for
pointer.getNode() whether it is null but the pointer itself is not
null...

Hmm...

There is, of course, a difference between the "no such property" and "the
property is there, but it is null" situations. In the latter case the
Pointer won't be null.

Give me more information and I'll try to investigate.

Thanks,

- Dmitri
