json array in request

[Alinto]

Hello,
i have to send a request to a restful api wich need a list in parameters. I do not find the way to create a DSRequest with a list which is not wrap in a record.

In a nutshell i get this :

param: [{index: "0", type: "DISCARD"}, {index: "1", type: "STOP"}]

and i would like this :

[{index: "0", type: "DISCARD"}, {index: "1", type: "STOP"}]

is it possible ?
Thanks for some help.
