PLease redirect this issue to the user forum, and provide sufficient info (esp. mapping documents). This is certainly not a bug in Hibernate (we have a test suite).

        Key: HB-507
    Summary: session.save() does not create records in child table for composite ids
       Type: Bug

     Status: Closed
   Priority: Major
 Resolution: REJECTED

    Project: Hibernate2
   Versions:
             2.1 beta 4

Description:
We have 2 persistent object, Highlight and HighlightLinks. Highlight object has one-to-many association to HighlightLinks with cascade="all", while the second one has composite id

<composite-id>
  <key-many-to-one name="highlight" class="Highlight" column="HIGHLIGHT_ID"/>
  <key-property name="offset" column="OFFSET" type="int"/>
</composite-id>

HighlightLinks object implements java.io.Serializable interface and equals()/hashCode() methods.

The code looks like:

Highlight highlight = new Highlight();
//Some setX() methods on highlight

highlight.setLinks(new HashSet());
HighlightLinks link = new HighlightLinks();

link.setOffset(linkItem.getIndex());
link.setHighlight(highlight);
//Some other setX() methods on link

highlight.getLinks().add(link);

//Some stuff here

session.save(highlight);

After this, the new record appears in HIGHLIGHT table, while HIGHLIGHT_LINK is empty.

As we can see from logs (show_sql is turned on), Hibernate is trying to update HIGHLIGHT_LINK table instead of inserting there.

We checked this issue on Hibernate 2.0.1 - it works (initially code was developed for this version). We found this issue in 2.1 beta 4.

We also checked out the latest code from CVS and the problem seems to still exist.

Thanks,
Mikheil
