Description of problem:

The error presents its self as: (curing a stack creation - that ends with a failure)

The template results in the error above however, upon stack delete the delete never processes. 

Version-Release number of selected component (if applicable): 7.0
How reproducible: 100% 

Additional info:

The only way, currently found to recover is to delete the resources, and then remove the entries in the database by hand, for the stack.

I had a look at the problem.

It seems the typo mentioned above in network_port.yaml is again the issue, when we're trying to show/delete the task.

Server resource uses it for the 'networks' property.

 test_instance:
    depends_on: [ssh_key, tennant_network, security_group, instance_port]
    type: OS::Nova::Server
    properties:
      name: {get_param: instance_name}
      key_name: { get_attr: [ssh_key, key_name] }
      image: {get_param: image_name}
      flavor: {get_param: image_flavor}
      networks:
        - port: {get_attr: [instance_port, port_resource]} >>> here
      availability_zone: {get_param: az}

As 'port_resource' is not resolved and returns a map, 'get_attr' fails, when finding dependencies[1] for the server during delete/show.
