Subject [jira] [Commented] (SOLR-6510) select?collapse=... - fix NPE in Collapsing(FieldValue|Score)Collector
Date Fri, 12 Sep 2014 18:29:35 GMT

    [ https://issues.apache.org/jira/browse/SOLR-6510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14131883#comment-14131883

Joel Bernstein commented on SOLR-6510:
--------------------------------------

Thanks for the patch Christine. 

It looks I can call the FieldCache.getTermsIndex() and it should protect against the null.
I'll test that out. If that works, I'll just remove the direct call to AtomicReader.getSortedDocValues(),
which was probably never needed in the first place.
