@acote-coveo By the way, why simply using fileMultiParams instead of fileParams doesn't work?

from scalatra.

@takezoe I don't know how it's map at the Swagger level but we support only one file param, not multiple values. We simply don't know what could be the filename passed and this is why we need to be able to get the first values without know the key(filename).

@acote-coveo Sorry for my late reply. I just thought you can write as follows regardless it's a single value param or multiple values param:

fileMultiParams.iterator.foreach { case (fileName, params) =>
  println(s"${fileName}: ${params.headOption}")
}

Anyway, having .iterator on FileSingleParams makes sense. Thanks for your contribution!
