This is not new, and may belong with the hibernate people (just tell me).
Using windows XP, latest daily build of JBT 3.
Have a mysql database with a fixed width field STATE char(2) and some varchar
fields. (mysql shows the column type for STATE as char(2))
Seam gen entities generates (in the code)
@Column(name = "STATE", length = 2)
@Length(max = 2)
(similarly for the varchar fields, no difference other than the 2 lengths)
In the persistence.xml, seamgen generates
Application fails to load with following traceback (partial):
Caused by: org.hibernate.HibernateException: Wrong column type: STATE,
expected: varchar(2)

I note that in the JBDS 2 Beta 1, the persistence.xml is autogenerated with
update, not validate. I can make the error go away by adding
columnDefinition="char(2)" to the column attribute.
I guess I feel generate entities should generate correct entities in the
presence of fixed length character fields.
