Dan Haywood created ISIS-1512:
---------------------------------
Summary: MetaModelValidator should detect domain objects that have
collections, and fail-fast.
Key: ISIS-1512
URL: https://issues.apache.org/jira/browse/ISIS-1512
Project: Isis
Issue Type: Improvement
Components: Core
Affects Versions: 1.13.0
Reporter: Dan Haywood
Assignee: Dan Haywood
Priority: Minor
Fix For: 1.13.1
this issue arose because attempting to download the metamodel.csv threw an
exception when it encountered an invalid class (specifically,
EstatioFakeDataService):
{code}
@DomainService(nature = NatureOfService.DOMAIN)
