Hibernate version:
3
Mapping documents:

<hibernate-mapping package="org.data">
<class
name="Projects"
table="projects"
>
...

<set name="modules" table="projectmodules" lazy="false" cascade="all">
<key column="pid"/>
<many-to-many column="mid" class="org.data.Modules"/>
</set>

...
</class>
</hibernate-mapping>

Code between sessionFactory.openSession() and session.close():

saveOrUpdate, update

Name and version of the database you are using:

mysql 4.1

Issue:

When code calls update with a Project object where modules set has been updated, the debug log shows the Module table is being updated. I need to make sure the projectmodules table is updated.

I'm trying <set table="xyz"> from the documentation. I'm hoping to avoid writing a Hibernate mapping file/objects for projectmodules table, since it is just storing the association between modules and projects.

Thoughts?

Seems to be an example straight out of the documenation in section 1.3.2. A unidirectional Set-based association.

But, the "projectmodules" table isn't being updated. I believe this is analogous to the "person_event" table

It's also appears to be like "23.4.3. Many-to-many with shared composite key attribute" in the documentation.

Anyone?

It seems like people would run into this situation more often.

The way I've dealt with this in the past is to actually create a pojo for projectmembers, but felt like it was hack-ish.

I made an incorrect reference based on the orig post: "projectmembers" should have been "projectmodules" in previous post

Hey Todd, it's Todd! How you doing pal?

Try removing the "cascade" attribute.
