Subject JSONRequestWriter
Date Wed, 05 Mar 2008 14:29:10 GMT
We're using localsolr and the RubyResponseWriter.  When we do a request with the localsolr
component 
in our requestHandler we're seeing issues with the display of a multivalued field when it
only has 
one value.

'class'=>['showtime']'showtime',      <------
'genre'=>['Drama',
  'Suspsense/Triller'],

With no localsolr component it works fine.

Looks like the issue is with the JSONRequestWriter.writeSolrDocument().  Here's the small
patch for 
it that seems to fix it.

        if (pseudoFields !=null && pseudoFields.size()>0) {


We're running solr trunk r614955 (Jan 23rd), and r75 of localsolr.

Result snippet with the patch:

'class'=>['showtime'],
'genre'=>['Drama',
  'Suspsense/Triller'],

Has anyone come across an issue like this?  Is this fixed in a newer build of Solr?   It looks
like 
we'd still need this patch even in a build of the solr trunk from yesterday, but maybe not.
