Re: [Hibernate] New error on Annotation query
From my understanding in discussions with Max, auto-discovery is illegal
once any returns have been defined/added.
Max, can you clarify here? Thinking some more about it, maybe you just
meant the column name discovery (as it should be possible to still
auto-discover types in this scenario)?
Also, in general, we need to make certain that these types of
integration point tests are defined within the Hibernate test suite
proper so that we can catch these discrepancies earlier...

[Hibernate] Contributor for tools template
A Freemarker template for Hibernate Tools that can generate DBUnit ReplacementDataSet XML descriptors would probably be very useful to many people. Is there anybody interested in contributing such a thing? ___ hibernate-devel mailing list hibernate-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/hibernate-devel

Yes - autodiscover of scalar types should always be
possible.
name discovery is only possible activated when nothing
is added to the query.
Also, in general, we need to make certain that
these types of"integration point tests" are defined within the Hibernate
test suiteproper so that we can catch these discrepancies
earlier...
I dont have a working setup here at the moment - but there
definitly should be test for this part.
But maybe this specific case of mixed add's might be
missed.

[Hibernate] Hbm2Java and custom-type problem in Hibernate-3/Hib-tools:3.1.0.beta4
Greetings, I am in the process of migrating my project code base to Hibernate-3 and having quite trouble with the way hibernate-tool in Hibernate3 work's with the CustomUserType's defined. The version of hibernate being used is 3.1.3 and hibernate-tools is 3.1.0.beta4 Working version (old): In Hibernate2, on invocation of hbm2java the following property in my *.hbm.xml property column=LAST_MODIFIED length=11 name=lastModified type=com.company.hibernate.usertypes.LastModifiedColumnType meta attribute=use-in-tostringtrue/meta meta attribute=default-valuenew java.util.Date()/meta /property gets converted to the following /** nullable persistent field */ protected Date lastModified = new java.util.Date(); which was correct all the interfaces with setters and getters were written accordingly. e.g: public void setLastModified(java.util.Date dt), public Date getLastModified(); NEW: In Hibernate-3, on invocation of the new hibernate-tool that wraps hbm2java, the same snippet from *.hbm.xml results protected LastModifiedColumnType lastModified = new java.util.Date(); and hence all the code base breaks on the compile step coz = found : com.company.hibernate.usertypes.LastModifiedColumnType required: java.util.Date I have several other custom type's and I am not sure how this can be fixed so that I can reuse my custom type(s). Is this a hibernate-tool (hbm2java) bug in 3.1.0.beta-4 or is there a right way to accomplish the same as in HIbernate-2. Thanks for reading! Appreciate if any one can help. ___ hibernate-devel mailing list hibernate-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/hibernate-devel
