Subject [jira] [Commented] (SOLR-7879) Null pointer exception when
Date Thu, 06 Aug 2015 16:05:05 GMT

    [ https://issues.apache.org/jira/browse/SOLR-7879?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14660214#comment-14660214
] 

Yonik Seeley commented on SOLR-7879:
------------------------------------

OK, you can only sort on "index", "count", or a calculated metric in the "facet" block.
So I'm assuming that the variable "sortCol" is one of avg_f1, avg_f2, unique_f3
But the problem here looks like sub_facet... it's sorting by "field3", but there's no "field3"
being calculated in that facet.
