HI alls.

I've got 3 tables.

Company (id, name)
Property(id, name, ref_id, lang_id)
Language(id, name)

in Company class;
public class Company {
private List properties;

/**
* @hibernate.bag inverse="false"
* table="multilanguage_property"
* lazy="false"
* cascade="all"
* inverse="true"
* where="disc like 'comp'"
* @hibernate.collection-key column="ref_id"
* @hibernate.collection-one-to-many
* class="com.clearview.feedback.db.language.MultiLanguageProperty"
* @return
*/
public List getProperties() {
return properties;
}

public void setProperties(List properties) {
this.properties = properties;
}
}

when i try to execute such code

Company company = new Company();
ArrayList prop = new ArrayList();
MultiLanguageProperty nameProperty =
new MultiLanguageProperty("kuku",
null, Language.getLanguage("en", session));
prop.add(nameProperty);
company.setProperties(prop);
session.saveOrUpdate(company); <----- here is exception

I get an exception: net.sf.hibernate.HibernateException: SQL update or deletion failed (row not found).

Because Hibernate is trying to execute SQL UPDATE but not SQL INSERT.

If i try to add to property list more than one Property, i get such exception:
net.sf.hibernate.HibernateException: Another object was associated with this id (the object with the given id was already loaded): [com.clearview.feedback.db.language.MultiLanguageProperty#0]

Company company = new Company();
ArrayList prop = new ArrayList();
MultiLanguageProperty nameProperty =
new MultiLanguageProperty("kuku",
null, Language.getLanguage("en", session));
MultiLanguageProperty nameProperty =
new MultiLanguageProperty("kuku",
null, Language.getLanguage("fr", session));
prop.add(nameProperty);
company.setProperties(prop);
session.saveOrUpdate(company); <---- here is exception

How can i solve this problem. Thank's

This is a FAQ!


set unsaved-value="0"

It didn't help. But when i changed "long id" to "Long id" and set unsaved-value="null", everything is ok.

I am *quite* certain that unsaved-value="0" would work, if you put it everywhere that is needed ;)

Maybe it should work but in my case it doesn't work.
I just change long -> Long and unsaved-value="0" -> unsaved-value="null" and it works.
Maybe i have crooked hands or maybe there's a bug.

There is no bug. Most likely you are not *really* using the mapping you think you are using.


Trust Me. This is VERY well-unit-tested. It can't possibly break. It is a mistake at your end.

gavin is right.it's not bug in hibernate.I did the same mistake by declaring as primitive type and my unsaved value = null and when i called save() it was sending wrong sql,after changing to 0 everything was working fine.
