Subject [jira] Updated: (SOLR-1021) NullPointerException in FieldStatsInfo
Date Fri, 06 Mar 2009 23:46:56 GMT

     [ https://issues.apache.org/jira/browse/SOLR-1021?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Rohit Gandhe updated SOLR-1021:
-------------------------------

    Attachment: SOLR-1021.patch

This patch contains Arie's fix and an additional (related) fix I had to make when extracting
facet info in QueryResponse. As he mentioned earlier, the NPE is thrown when trying to extract
stats and facets from a resultset which contain 0 docs.

> A NullPointerException is thrown at line 51 of class FieldStatsInfo since the returned
stats information for the fname (ctor variable) is null and not checked for being so.
> Seems like this occurs when the search returns with no results but there were some setGetFieldStatistics
defined for some fields.
