Gail Badner commented on HHH-7100:
----------------------------------
This causes problems when collection table primary and foreign keys are created.
ColumnAttributeSourceImpl.isNullable() returns true for collection
key and basic element columns
------------------------------------------------------------------------------------------------
Key: HHH-7100
URL: https://hibernate.onjira.com/browse/HHH-7100
Project: Hibernate ORM
Issue Type: Bug
Components: metamodel
Reporter: Gail Badner
Fix For: 5.0.0
Not absolutely sure about this, but I think ColumnAttributeSourceImpl.isNullable() should
return:
- TruthValue.UNKNOWN for collection key column.
- TruthValue.UNKNOWN for a basic collection element column, unless explicitly specified
in the mapping
If ColumnAttributeSourceImpl.isNullable() returns TruthValue.UNKNOWN, then
ColumnBindingDefaults.areValuesNullableByDefault() can be used to provide the proper
default.
