NPE in DataBuilder.stripNS() during RESTPost.run() with rest:context provided
Howdy -- I'm getting a stack trace putting the following query (exact, unmodified) through the REST POST interface on a BaseX snapshot as of this morning: $ curl -X POST -T - -H 'Content-Type: application/xml' \ http://admin:admin@localhost:8984/rest <<EOF <rest:query xmlns:rest="http://basex.org/rest"> <rest:text> / </rest:text> <rest:context> <root> <foobar:root xmlns:foobar="http://example.com/foobar"> <foobar:b/><foobar:b/><foobar:b/> </foobar:root> </root> </rest:context> </rest:query> EOF Unexpected error: null (yes, it requires _three_ of the <foobar:b/> elements before this happens -- execution is fine with just two) Improper use? Potential bug?

..I managed to reproduce this issue; seems to be related to [1], so I guess it has been recently introduced with a snapshot. I'll give you feedback soon. Christian ___________________________ On Fri, Feb 24, 2012 at 3:58 AM, Charles Duffy <charles@dyfis.net> wrote:

Dear Charles, the problem should now be fixed, just as the issue reported by Andy [1]. Once again, you are invited to check out the latest snapshot [2]. Christian [1] https://github.com/BaseXdb/basex/issues/397 [2] http://files.basex.org/releases/latest/ ___________________________
