Hi,

I'm trying to implement some simple multilanguage support, but have failed so far.. perhaps someone here can give me a clue.

The setup, stripped down to the relevant information, is very simple: A Tour object can have a title and a description, available in multiple languages.

The database-setup is like this:

create table TOUR_TOUR(
ID INTEGER not null,
...)

create table TOUR_TEXT(
TOUR_ID INTEGER not null,
LANGUAGE VARCHAR(2) not null,
TITLE VARCHAR(80) not null,
DESCRIPTION VARCHAR(500) not null)

For TOUR_TEXT, a class named TourText with getters/setters for all the fields exists. The class Tour contains a set of instances of TourText, also accessible with setText(Set tourtext) and the matching getter.

Here's my hibernate mapping for this scenario:

<class name="Tour" table="TOUR_TOUR">

<!-- irrelevant lines stripped -->

<set name="text" table="TOUR_TEXT" inverse="true" lazy="true">
<key column="ID"/>
<one-to-many class="TourText"/>
</set>

</class>


<class name="TourText" table="TOUR_TEXT">
<composite-id >
<key-property name="id"/>
<key-property name="locale" column="LANGUAGE"/>
</composite-id>

<property name="title" column="title"/>
<property name="description" column="description"/>
</class>

In a JUnit test, I create a new Set with a single TourText object, assign it to a newly created tour, and make it persistent. However, only the tour object shows up in the database itself - no tourtext tupel is being created. I switched all logging to debug, but there are no error messages.

If somebody has any idea what's missing, I'd highly appreciate that!

Regards,
sen

Just discovered this article on the hibernate wiki('Some Parent-Child Principles'):

This should do nicely, going to try it at asap..
