I'm having a problem with using strict dynamic mapping and multi-field  
values. My multi fields work fine when I don't have StrictDynamicMapping  
enabled but when I enable it I get the error

"error": "StrictDynamicMappingException[mapping set to strict, dynamic  
introduction of [email.downcased] within [External::User] is not allowed]"

The significant part of my index request looks something like this

PUT /test\_app\_9/External::User/12  
{  
"email": "john@john.com",  
"email.downcased": "john@john.com",  
"name": "John Doe",  
"name.downcased": "john doe",  
"browser\_locale": "en",  
.... all other attributes  
}

and the significant part of my mapping is as below. What am I doing wrong?

```
  "mappings": {
     "External::User": {
        "dynamic": "strict",
        "dynamic_templates": [
           {
              "string_custom_data": {
                 "mapping": {
                    "type": "multi_field",
                    "fields": {
                       "{name}": {
                          "index": "no",
                          "type": "string"
                       },
                       "downcased": {

                          "type": "string"
                       }
                    }
                 },
                 "match": "*_string"
              }
           },
           {

                    "type": "date"
                 },
                 "match": "*_date"
              }
           }
        ],
        "_all": {
           "enabled": false
        },
        "properties": {
           "app_id": {
              "type": "integer"
           },
           "browser_locale": {
              "type": "string",
              "index": "no",
              "fields": {
                 "downcased": {
                    "type": "string",
                    "index": "not_analyzed"
                 }
              }
           },
           "email": {
              "type": "string",
              "index": "no",
              "fields": {
                 "downcased": {
                    "type": "string",
                    "index": "not_analyzed"
                 }
              }
           },

```

Not one reply?  
I'm having similar issues and would like to know if you or anyone else has any hints on how to update a field with "dynamic": "strict" set on the index mappings.

I need to change a mis-spelled last name. For instance change Steward to Stewart w/o changing any other data or mappings.
