Change of scope 2018-02-23: Report references to non-existing and deprecated page template definitions and theme definitions. Both are referenced from site definitions.
Confirm that all problems with YAML definitions are reported to Definitions app
- Definitions which reference definitions which do not exist.(For example a template definition references a non-existent dialog definition)
Reported messages should say
- Which class / definition / whatever is deprecated / not found
Please note Magnolia's behaviour in those cases currently as a comment or in a wiki page.
Requirement in YAML backwards compatibility
