Hibernate version: 3

Name and version of the database you are using: Oracle 10g

Tables:
Task
Task_Attribute [having Task_id as foreign key in Task table]

Java entities:
Task [having a collection of 'TaskAttributes']

When we save a TaskEntity, Hibernate is doing both 'Insert' as well as 'Update' on 'Task Attribute' table for the same record.

As we have triggers on these table, Insert and Update triggers are being called when only 'insert' should have been called.

Hibernate Mapping:
<class name="Task" table="TASK">
.....
<bag name="attributes" table="TASK_ATTRIBUTE" cascade="all" lazy="false" inverse="false">
<key column="TASK_ID" not-null="true"/>
<one-to-many class="TaskAttribute"/>
</bag>
.....
</class>

Is there a way to avoid 'insert+update' by hibernate when its just 'inserting' task attribute?

Help highly appreciated.

Thanks.

Try again with inverse="true" for 'attributes' collection.

Have a look at this:
