Hi Halvdan,

The following are the steps I'm using:
1. Save the file on the api/fileResource endpoint, get the UID back, then
save the uid as of a dataValue on the event. Example:

    POST to api/fileResources, get id: “a11111bbbb” back.
2. PUT the event:

{
  "event" : "<some-event-uid>",
  "dataValues" : [
    {
      "value" : "a11111bbbb",
      "dataElement" : "<some-fileResource-dataelement-uid>"
    }
  ]
}

Are these steps correct?
Are the datasets required in these case? If yes, how should I go about
doing this in the tracker module.

Regards,
Mike
