#15 NullPointerException when performing full text search

[Bjřrn Wang]

Hello,

I have problems with dbXML throwing a
NullPointerException every time I try performing a full
text query.

I've added test documents and a full text index
(pattern=*), and issue the following query:

<dbxml:fulltext
xmlns:dbxml="http://www.dbxml.com/db/query" xpath="">
<select name="*">bringes</select>
</dbxml:fulltext>

dbXML reports the following error:
