[jira] [Commented] (SOLR-4647) Grouping is broken on docvalues-only fields

["David Smiley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-4647?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13623667#comment-13623667 ] 

David Smiley commented on SOLR-4647:
------------------------------------

There seems to be a need for a String-to-value method on FieldType.  Based on the current method names, its signature should be Object toObject(String str).  By default it could return str directly.

> There are a few places where grouping uses FieldType.toObject(SchemaField.createField(String, float)) to translate a String field value to an Object. The problem is that createField returns null when the field is neither stored nor indexed, even if it has doc values.
> An option to fix it could be to use the ValueSource instead to resolve the Object value (similarily to NumericFacets).
