[ http://jira.codehaus.org/browse/XDP-133?page=comments#action_76913 ] Konstantin Pribluda commented on XDP-133: -----------------------------------------
Typedef tag is honored only on root of persistent class hierarchy ( entity ), so please place it there. Though if you dare to provide patch to gather all the typedefs from persistent class hierarchy it will be accepted. When we get time we may get back to this issue, so it remains open but as an improvement. Forsing regeneration when subclasses change would require substantial patching, and gets own improvement insue ( feel free to provide patch too ) > Omitted @hibernate.typdef tag in a @hibernate.joined-subclass > ------------------------------------------------------------- > > Key: XDP-133 > URL: http://jira.codehaus.org/browse/XDP-133 > Project: XDoclet 2 Plugins > Issue Type: Bug > Components: hibernate > Affects Versions: 1.0.2 > Environment: Windows XP, ANT 1.6.5, Eclipse 3.1.1 > Reporter: Christoph Adl > > The problem is that if I use the @hibernate.typdef tag in a > @hibernate.joined-subclass tag it does not lead to any XML output in the > generated mapping file.

This problem is probably a result of the fact, that the > DerivedClass-Mapping must be included in the mapping file of BaseClass (a > speciality of the Hibernate DTD). The solution is, to create the > typedef-element in BaseClass.hbm.xml outside the class element (this must > happen for the whole inheritance tree - so for joined-subclass elements in > joined-subclass elements as well).
