Validating a stack fails as one nested stack can't find an id from another

[Brett Osteen]

Upstream bug report.

In this example, a parent stack is creating a subnet in one nested stack and a loadbalancer in another:

resources:

  network:
    type: Test::Network

  load_balancer:
    type: Test::LoadBalancer
    properties:
      private_subnet: {get_attr: [network, private_subnet_id]}
    depends_on: network

Validation will fail in this case (and stack will not start creating) with this error:

RESP BODY: {"explanation": "The server could not comply with the request since it is either malformed or otherwise incorrect.", "code": 400, "error": {"message": "Failed to validate: : resources.load_balancer: : At least one of the following properties must be specified: subnet, subnet_id", "traceback": null, "type": "StackValidationFailed"}, "title": "Bad Request"}

This was tested on version 0.8.0 and it was working on previous versions (I'm using the same templates for the past 2 major openstack versions)

Brett, is this procedure somehow documented in Mirantis' docs?

@oleksiy Is there any updates on this issue? Can you please give some explanation as to why it was moved to incomplete?
