Description

When using the JSON API, faceting on an EnumField or TrieIntField returns an empty list of buckets.

Steps to reproduce:
1. Define an EnumField.
schema.xml:
<field name="kingdom" type="kingdomEnum" indexed="true" stored="true" required="true" />
<fieldType name="kingdomEnum" class="solr.EnumField" enumsConfig="enumsConfig.xml" enumName="kingdom"/>

enumsConfig.xml:
<?xml version="1.0" ?>
<enumsConfig>
<enum name="kingdom">
<value>plants</value>
<value>metazoa</value>
<value>fungi</value>
</enum>
</enumsConfig>

2. Add documents to core.

3. Faceting over the EnumField returns an empty list of buckets:
$ curl http://localhost:8983/solr/myCore/query -d '
{
query: ":",
facet : {
kingdom :

{terms : kingdom}

}
}'
{ ...
"facets":{
"count":17,
"kingdom":

{ "buckets":[]}

}}

The same issue happens with TrieIntField. Using old-style facets works, this only happens with the new JSON API.

I tested changing the field to a string and I get the expected results.
