Howdy,
I am using Hibernate 2.1.8 within weblo.
I have an object A having a "set" relation with an object B. I noticed that when I change only one attribute from my object B, hibernate updates all the attributes of B and not only the one that have been changed. I am wondering if there is a way to oblige hibernate to update only the attribute that have been changed.
best regards.

You can set the mapping for Object B to use dynamic-update. Something like

Code:
<?xml version="1.0"?>

<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping package="com.starwood.valhalla.poe.marketing.vo">   
   <class name="ObjectBClass" table="Object_B" dynamic-update="true">   
    .....
   </class>


this will generate required update queries for your situation. I dont know if this attribute is also available in version 2.1.8 but you can verify in the DTD.
