Yup.. that's how I got the saves working before... here is my setup...
<hibernate-mapping default-cascade="save-update">
<class name="eightotwo.fhe.model.content.hibernate.HibernateCategory"
table="CATEGORY">
<id name="id" column="categoryid" type="long">
<generator class="hilo.long"/>
</id>
<property name="active" column="active" type="boolean"/>
<property name="description" column="description" type="string"/>
<property name="name" column="name" type="string"/>
<property name="conception" column="conception" type="timestamp" />
<one-to-one name="parentCategory"
class="eightotwo.fhe.model.content.hibernate.HibernateCategory"/>
<!-- need note mappings -->
<list role="notes">
<key column="category_noteid"/>
<index column="listorder"/>
<one-to-many
class="eightotwo.fhe.model.audit.hibernate.HibernateNote"/>
</list>
<!-- creator -->
<many-to-one name="creator"
class="eightotwo.fhe.model.security.hibernate.HibernateAdministrator"
column="admincreatorid"/>
</class>
</hibernate-mapping>
then here is the HibernateNote object..
<hibernate-mapping default-cascade="none">
<class name="eightotwo.fhe.model.audit.hibernate.HibernateNote"
table="NOTE">
<id name="id" column="noteid" type="long">
<generator class="hilo.long"/>
</id>
<property name="comment" column="comment" type="string"/>
<property name="date" column="commentdate" type="timestamp"/>
<!-- need to keep track of who set this note, must be admin -->
<many-to-one cascade="none" name="user"
class="eightotwo.fhe.model.security.hibernate.HibernateAdministrator"
column="administratorid"/>
</class>
</hibernate-mapping>
I have been playing around for a bit.. but the problem that I am having now
is that when I call the following code:
category = CategoryDAOFactory.getDAO().findById(id);
Note note = NoteDAOFactory.getDAO().newNote();
User user =
UserManagerFactory.getManager().findAdministratorById(getUser().getId());
note.setUser(user);
note.setComment(comment);
List notes = category.getNotes();
notes.add(note);
category.setNotes(notes);
ContentManagerFactory.getManager().update(category);
---
update more or less calls category.saveOrUpdate();
the the category object gets saved again.. and now I have to category
objects... each time I add a note and save the category this problem
happens... am I just missing the correct way to have the cacades setup?
Thanks,
Justen Stepka
