Actually, it was Doug's implementation of the XPath view, if memory serves me correctly.
JAXP has a pretty stupid API when it comes to result values, since we have to specify up front if we want a nodeset (which we prefer for the view) or a string (which is needed for simple expressions). A clumsy workaround is supplied in the version in CVS.
Jaxen fixes this by returning an Object which is then examined and displayed accordingly.
The secondary issue is for opening up the XPath parser or parse tree, for validation and completion purposes. But for that, I'll have a hard look at the BPEL XPath stuff. And I doubt I'm going to have time to get this in place anytime soon.

No immediate need at all. JAXP will do the trick as supplied, if clumsily.
Thanks, Jesper
