I'm not sure if I missed something but when creating a group of servers via the heat command line using the following template i get multiple servers with the name ob-devp-app-%index% instead of ob-devp-app1,ob-devp-app2,etc.....

heat_template_version: 2013-05-23

description: Template to deploy a number of servers

parameters:
  pdc_app_server_count:
    type: number
  pdc_app_server_image:
    type: string
  pdc_app_server_flavour:
    type: string

resources:
  pdc_app_servers:
    type: OS::Heat::ResourceGroup
    properties:
      count: { get_param: pdc_app_server_count }
      resource_def:
        type: OS::Nova::Server
        properties:
          name: ob-devp-app-%index%
          image: { get_param: pdc_app_server_image }
          flavor: { get_param: pdc_app_server_flavour }
          networks:
            - network: "fixed"

I've tried various different formats for the name property(enclosed in ",using _ as the sperator) but nothing seems to be working. reading the template guide I can't see anything obviously wrong with the template so I'm a bit stuck now. http://docs.openstack.org/developer/heat/template_guide/openstack.html#OS::Heat::ResourceGroup (http://docs.openstack.org/developer/h...)
