Update API - how to remove inner fields from objects via script?

Elastic Stack Elasticsearch
1

I have an index that supports dynamic mappings under a field of type Object
that we named custom. My doc also has other objects properties with inner
props. I attached an abbreviated mapping - notice my object for "realm"
and it's properties

Using the Update API I can remove a field per the docs
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/docs-update.html
if it's a top level field. For example this works great:

POST
/test-timbr-2015.02.19/event/0f78c6b6-a30b-436e-bad7-4234654fc5bb/_update
{
"script" : "ctx._source.remove("threadid")"
}

However, when I run the script against a document that has a field nested
in a specific object graph the specified field doesn't get deleted. I'm
using dot notation as you can see, and when I run this ES comes back with a
HTTP 200 and the _version property gets incremented.

POST
/test-timbr-2015.02.19/event/0f78c6b6-a30b-436e-bad7-4234654fc5bb/_update
{
"script" : "ctx._source.remove("realm.name")"
}

How can I get inner properties like this removed via the Update API.

Thanks for your help.

Nevermind folks thanks anyway. I took a look at the ES source. Each
object in the doc has it's own methods such as remove():

POST
/test-timbr-2015.02.19/event/0f78c6b6-a30b-436e-bad7-4234654fc5bb/_update
{
"script" : "ctx._source.realm.remove("name http://realm.name/")"
}
