Swagger UI not sending array correctly

Question

I am trying to send multiple values (an array) (refer to on line 93 in spec ->... name: recipients[] ...)

The problem I am facing is the Swagger-ui call the endpoints as below:

Actual

recipients[]=value1%2Cvalue2

Expected

recipients[]=value1&recipients[]=value2

The %2C means , (comma).

Below are the required details swagger-ui version 2.1.1 Below is the link for content of the swagger spec file reproducing the issue: http://pastebin.com/V3ZuCjVz

It looks like the way to specify this is to add collectionFormat: multi

- name: recipients[]
  in: formData
  description: Email addresses for recipients (multiple values allowed).
  required: true
  type: array
  collectionFormat: multi
  items:
      type: string

Possible values from http://swagger.io/specification/ are:

• csv - comma separated values foo,bar.
• ssv - space separated values foo bar.
• tsv - tab separated values foo\tbar.
• pipes - pipe separated values foo|bar.
• multi - corresponds to multiple parameter instances instead of multiple values for a single instance foo=bar&foo=baz. This is valid only for parameters in "query" or "formData".
