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

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/
