I made a simple example that fails. Maybe my example is a
misinterpretation of what you said:
tosca_definitions_version: tosca_simple_yaml_1_0
imports:
- aria-1.0
data_types:
d1:
properties:
p1:
type: string
d2:
derived_from: d1
properties:
p2:
type: string
node_types:
T1:
derived_from: tosca.nodes.Root
properties:
n1:
type: d1
T2:
derived_from: T1
properties:
n1:
type: d2
This produces the error:
4: override changes type from "d1" to "d2" for property "n1" in "T2
