Outputs do not show for some lists

[catsby]

Trying to output the private IPs of an AWS Network Interface, but nothing is rendered:

Config:

provider "aws" {
  region = "us-east-1"
}

resource "aws_vpc" "default" {
  cidr_block = "10.40.0.0/19"
  tags {
    Name = "tf-eni-test"
  }
}

resource "aws_subnet" "private" {
  vpc_id            = "${aws_vpc.default.id}"
  availability_zone = "us-east-1a"
  cidr_block        = "10.40.0.0/22"
  tags {
    Name = "tf-eni-test"
  }
}

resource "aws_network_interface" "router" {
  subnet_id = "${aws_subnet.private.id}"
  tags {
    Name = "tf-eni-test"
  }
}

output "router" {
  value = "${join(",", aws_network_interface.router.private_ips)}" # outputs nothing
}

output "subnet" {
  value = "${aws_network_interface.router.subnet_id}"
}

Produces:

$ terraform apply
[everything creates successfully]

State path: terraform.tfstate

Outputs:

  subnet = subnet-ca80c593

Terraform show does show the private ips:

aws_network_interface.router:
  id = eni-53ae9c09
  attachment.# = 0
  private_ips.# = 1
  private_ips.1053885830 = 10.40.3.105

@catsby Does #2157 solve that problem?
