Hello,

I have the following document that's created as a new document.  
[http://localhost:9200/ibmbpm/doc/task2?pretty](http://localhost:9200/ibmbpm/doc/task2?pretty)

> {  
> "lastUpdate" : "2018-01-14T14:40:20.452-02:00",  
> "tasks" : {  
> "1" : {  
> "lastUpdate" : "2018-01-14T14:40:20.452-02:00",  
> "taskId" : "1",  
> "subject" : "My first task",  
> "status" : "Active"  
> },  
> "2" : {  
> "lastUpdate" : "2018-01-14T14:50:20.452-02:00",  
> "taskId" : "2",  
> "subject" : "My second task",  
> "status" : "Active"  
> },  
> "3" : {  
> "lastUpdate" : "2018-01-14T14:55:20.452-02:00",  
> "taskId" : "3",  
> "subject" : "My third task",  
> "status" : "Active"  
> }  
> }  
> }

So I'll execute an update that add a substructure inside a specific task (in this case the first task)  
[http://localhost:9200/ibmbpm/doc/task2/\_update?pretty](http://localhost:9200/ibmbpm/doc/task2/_update?pretty)

> {  
> "doc": {  
> "tasks": {  
> "1": {  
> "assign" : [  
> {  
> "date" : "2018-01-14T14:40:20.452-02:00",  
> "type" : "user",  
> "name" : "t\_rmazili",  
> "id" : "295"  
> }  
> ]  
> }  
> }  
> }  
> }

Now I need to add another child inside assign structure (it's an array), but update or new document only with the structure presented on the second requisition will replace the first child, not add a new one... how can I append a new child inside assign value instead of replace it?

I really appreciate any help  
Thanks

Solved with the following update.

> {  
> "script": {  
> "inline": "ctx.\_source.tasks.1.assign.add(params.assigned)",  
> "params" : {  
> "assigned" : {  
> "date" : "2018-01-14T14:40:20.452-02:00",  
> "type" : "user",  
> "name" : "t\_daniele",  
> "id" : "334"  
> }  
> }  
> }  
> }
