I'm using the event api to filter the data collected from various beats.

response

object:

> ```
> {
> "a" : "random",
> "b": [
> { 
> "a1" : "aone"
> }
> ,
> {
> "a2": "atwo"
> }
> ]
> }
> 
> ```

when i run some thing like

> ```
> filter{
> ruby{
> code => "puts(event.get('[response][b]'))"
>        
> }
>  
>  
> }
> 
> ```

```
it returns {"a1":"aone"}{"a2":"atwo"}
instead of [{"a1":"aone"},{"a2":"atwo"}]

```

It does return an array, but puts of an Array does not do what you expect

```
    ruby {
        code => '
            b = event.get("[response][b]")
            if b.kind_of? Array
                puts "b is an Array"
            end
            puts "puts of b -- "
            puts b
            puts "puts of b.to_s -- "
            puts b.to_s
        '
    }

```

produces

```auto
b is an Array
puts of b --
{"a1"=>"aone"}
{"a2"=>"atwo"}
puts of b.to_s --
[{"a1"=>"aone"}, {"a2"=>"atwo"}]

```
