> Hi,
> I've posted this issue about 3 weeks ago on the solr-user mailing list here: 
> http://mail-archives.apache.org/mod_mbox/lucene-solr-user/201601.mbox/%3C568EEF90.8050100%40gmail.com%3E
> Basically, when using the json facet api on an enum field, like this:
> {noformat}
>     json.facet={
>       states: {field: state}, dates: {field: insertdate}
>     }
> {noformat}
> where state is an enum, i get an error:
> {noformat}
>   "error":{
>     "msg":"Expected numeric field type
> :state{type=auState,properties=indexed,stored,docValues}",
>     "code":400}
> {noformat}
> The full example can be found here: https://gist.github.com/xou/33fd7aab7afe3cebb28b
> And a quick-and-dirty patch can be found here: http://bildungsresistenz.de/tmp.h/0001-Added-support-for-facetting-on-enum-types.patch
> I'm not sure whether the patch is the right way to approach this; if it goes in the right direction i can definitely try to clean it up a bit more.
> Cheers,
> Niko
