Hi, I'm trying to update an object inside an  
{  
...  
arrayKey: [{  
key1: value1,  
key2: value2  
}  
]  
...  
}

The objective is to change the value of **key1**. The only way I could find to do it, is to replace the entire object with the following:

```
   String objectValue = new ObjectMapper().valueToTree(fieldValue.get(0)).toString();
        XContentParser parser = JsonXContent.jsonXContent
                .createParser(NamedXContentRegistry.EMPTY,objectValue);
        contentBuilder.startArray(fieldName);
        contentBuilder.copyCurrentStructure(parser);
        contentBuilder.endArray();

```

Is there a better way? Thanks!
