[jbosstools-issues] [JBoss JIRA] Commented: (JBIDE-4201) Discriminator of RootClass is not exported.

Dmitry Geraskov commented on JBIDE-4201:
----------------------------------------
When I was working under this bug I found interesting thing:
when used xml mapping discriminator is required for such hierarchy mapping,
but it is not required when annotation mapping used.
For annotation mapping hibernate itself creates discriminator value with
"string" type and "DTYPE" column when @Discriminator is not set.
Why we have such inconsistency?
Discriminator of RootClass is not exported.

Key: JBIDE-4201
URL: https://jira.jboss.org/jira/browse/JBIDE-4201
Project: Tools (JBoss Tools)
Issue Type: Sub-task
Components: Hibernate
Affects Versions: 3.0.0.GA
Reporter: Dmitry Geraskov
Assignee: Max Rydahl Andersen
Fix For: 3.1.0.M1
Attachments: patch.txt
RootClass.discriminator value used to determine discriminator type and columns when
table-pre-type-hierarchy used in mapping, but element discriminator never exported and
sessionFactory can't be built for such configuration:
org.hibernate.MappingException: No discriminator found for com.jboss.dvd.seam.Admin.
Discriminator is needed when 'single-table-per-hierarchy' is used and a class has
subclasses
