Summary: forced cmp-field init during create
Initial Comment:
windows 2000; jdk1.3.1_01; JBoss 3.0.0DR1(2-13-2002; GMT 10:00);
Hi,
i tried to create instance of an entity bean, but all i got was exceptions until i
initialized all cmp
fields during the ejbCreate() method of that bean. such a bug is not really severe
because an
initialization should always be possible (at least with default values) but according
to the ejb
specification the application provider does not have to initialize the cmp-fields. i
checked whether
the problem is in the database or in Jboss... the db allows creation of rows such as
(xyz, null, null)
- Jboss not! when encountering a null valued cmp-field the process of sql query
composition stops
and the creation of the bean instance is unsuccessful - see log output. (this was the
actual
problem of bug #516404 "invalid type mapping")

seems like there's a problem in org.jboss.ejb.plugins.cmp.jdbc.JDBCUtil at line 144
btw.: my "old" version of JBoss 3.0.0DR1 managed to create the tables itself by using
the specified
type mapping - the new one (from this morning) doesn't - any clue?
Thanks for the support yesterday!

What database and type-mapping are you using?
