Unable to parse text exception with in models with `group-as/@in-json="SINGLETON_OR_ARRAY"` behavior #221

aj-stein-gsa · 2024-10-28T21:48:01Z

Describe the bug

When using metaschema-java in the latest stable version to deserialize models with fields (not assemblies) with the group-as/@in-json="SINGLETON_OR_ARRAY", you will consistently receive a java.io.IOException: Unable to parse field value as text exception.

This an invalid model because of the conflicting requirements between the parent max-occurs and the inner group-as. When max-occurs="1" is set outside such a group-as, the latter is ignored by the metaschema-java core parser.

Dave is going to write improved error messaging around this issue in the metaschema-core related to this poor incorrect model defintion.
AJ to write constraints in the Metaschema module module to give a hard error for group-as/@in-json as ARRAY or SINGLETON_OR_ARRAY where parent max-occurs MUST be greater than 1 exclusive (2 to unbounded).

Changed expected behavior in unit test to provide null values in JSON and empty values in XML, which is consistent with current behavior. Improved error handling for data type conformance issues. Related to GSA/fedramp-automation#823.
