Hello, I am using spring framework with HibernateSupport

Step_State table has composite-id and is a foreign key to CONTENT Table

So Ihave collection of contents defined in the StepState Class

what should i do to resolve unsaved transient instance ? hibernate saves into STEP_STATE table but does not save into Content table..

I am using saveOrUpdate(stepstateObject)

an object associated with the object you are saving is not saved first.
save it first manually are use the cascade="save-update" functionality.

in stepState mapping file I have he following
.. should i chjange from cascade="all" to cascade="save-update" ?
<set
name="contents"
lazy="false"
inverse="true" cascade="all"
>
<meta attribute="field-description">
@hibernate.set
lazy="false"
inverse="true"

@hibernate.collection-key
column="CON_GROUP_ID"
@hibernate.collection-key
column="CON_WRK_SESSION_ID"
@hibernate.collection-key
column="CON_STEP_ID"

@hibernate.collection-one-to-many
class="com.test.groupstate.hibernate.Content"
</meta>
<key>
<column name="CON_STEP_ID" />
<column name="CON_WRK_SESSION_ID" />

<column name="CON_GROUP_ID" />
</key>
<one-to-many
class="com.test.groupstate.hibernate.Content"
/>

</set>
