hi,
I am using hibernate 2.1 and sybase.this is my scenario


MovieLibrary
=============
ProgramID int
clientID int


composite key is (clientID,ProgramID)


mapping snippet for MovieLibrary is ---

<composite-id
name="movieLibraryPK"
class="MovieLibraryPK" >
<key-property name="clientID" column="clientID"/>
<key-property name="id" column="ProgramID"/>
</composite-id>

<set name="movies" cascade="all" inverse="true">
<key>

<column name="clientID" not-null="true" />
<column name="ProgramID" not-null="true" />
</key>
<one-to-many class="Movie" />
</set>



Movie
========

episodeID int
effectiveStartDate datetime
ProgramID int
clientID int

composite key is (episodeID,effectiveStartDate,clientID,ProgramID)

mapping snippet for Movie is ---

<composite-id
name="moviePK"
class="MoviePK" >
<key-property name="id" column="episodeID"/>
<key-property name="effectiveStartDate" column="effectiveStartDate"/>

<key-many-to-one name="movieLibrary" class="MovieLibrary">
<column name="clientID" not-null="true"/>
<column name="ProgramID" not-null="true"/>

</key-many-to-one>
</composite-id>


First of all is there any wrong with my complex mapping??
when I save session.save(movielibray);
movielibrary object is saved and I expect the childs "movies" also to be saved.But it is actually trying to update the movies and saying "batch update failed"count 0..

I didn't call saveOrUpdate() which I may call sometime later when some childs had to be inserted and some has to be updated.


Any help is greatly appreciated..
Thanks and Regards

read the doc. Cascadind always call saveOrUpdate. so set unsaved-value properly

thanks emmanuel!
I have kept unsaved-value="any" for the child.It inserted the parent i.e MovieLibrary and it even inserted the child i.e Movie(but in the Movie table column ProgramID is 0 ) It is not taking the ProgramID from the parent i.e MovieLibrary while inserting the child,Movie.

is this the problem because both my (MovieLibrary)parent and child (Movie)has composite keys??

Thanks and Regards for any help!

Does the appropriate entry (unsaved-value and composite-id) in the FAQ applies to your case ?

hi Emmanuel,
solved my problem, Thanks!
there was no problem with mapping,only with domain objects manipulation.

Regards
