resource creation failes with type error if derived from a parameter

[Removed by request]

I have a testing environment with several interchangeable and modular templates.
The 'parent' template calls other templates by using resource type: template.yaml.
I would like to be able to use different templates with the same parent for different test scenarios and so I have tried to do this:

parameters:
  networking:
    type: string
    default: simple.yaml
  server:
  .
  .
  .
  etc'

resources:
  network:
    type: {get_param: networking} <-- sometimes I'd like to use a different yaml without having to change the template manually...

This is probably not working, but the error in this case is misleading:
# heat stack-show test
.
.
.

| stack_status_reason | Resource CREATE failed: TypeError: Resource volume type
| | typemust be string

If this should not work on the first place, then this is a validation issue that should be caught earlier on.

Tested on 0.2.12

This is not expected to work, you should use the environment resource_registry instead.

We should fail fast though, at validation rather than create time.

Amit Ugol, I can't reproduce this bug on 0.2.12 and think, that https://review.openstack.org/#/c/134343/ fixes your problem. Can you try to reproduce your problem with this patch?

    Add resource_definitions check to Stack.validate

    We should check resource attributes' types in validate method
    for preventing stack creation with incorrect resources. So
    this patch splits resource_definitions() methods on
    validate_resource_definitions() and resource_definitions()
    methods and add validate_resource_definitions() to Stack.validate
    method.
