KeyError is raised in get_attribute validation in case of nested data types

[Miguel Caballer]

Having these two data types defined:

  tosca.datatypes.SomeTask:
    derived_from: tosca.datatypes.Root
    properties:
      state:
        type: string
      output:
        type: string

  tosca.datatypes.OtherTask:
    derived_from: tosca.datatypes.Root
    properties:
      tasks:
        type: map
        entry_schema:
          type: tosca.datatypes.SomeTask

And trying to access an attribute value similar to that

    ansible_output:
      value: { get_attribute: [ web_server, other_task, some_map, tasks, some_other_map, output ] }

This error is raised:

 KeyError: 'Illegal arguments for function "get_attribute". Attribute name "output" not found in "tosca.datatypes.OtherTask"'

It seems that validation does not access nested data type.

This issue was fixed in the openstack/tosca-parser 2.6.0 release.
