imo this method should look lik:
if ((objectOrProxy instanceof Proxy) && Proxy.isProxyClass(objectOrProxy.getClass()))
{
IndirectionHandler handler;
handler = (IndirectionHandler) Proxy.getInvocationHandler((Proxy) objectOrProxy);
return getKeyValues(cld, handler.getIdentity(), convertToSql); // BRJ: convert Identity
}
else if (objectOrProxy instanceof VirtualProxy)
{
IndirectionHandler handler;
handler = (IndirectionHandler) VirtualProxy.getIndirectionHandler((VirtualProxy) objectOrProxy);
return getKeyValues(cld, handler.getIdentity(), convertToSql); // BRJ: convert Identity
}
else
{
ClassDescriptor realCld = getRealClassDescriptor(cld, objectOrProxy);
return getValuesForObject(realCld.getPkFields(), objectOrProxy, convertToSql);
}

Yup, that was it. FieldConversions break backreferences. Verfied in both ODMG and PB. Any idea how I can fix that or were I can look.

Hi again,
FieldConversions could be a factor.
We have testcases for FieldConversions on PrimaryKey fields, but I think
no
tests for 1:n plus backreference + FieldConversion on foreignkey.
Can you modify your setup to test without fieldconversion?
cheers, thomas

Hi Thomas,
The test case runs fine, but my implementation is still failing using both ODMG and PB with auto-update/auto-retrieve set to true. I am using field conversions in my PK and FK fields. Could that be a factor?

Hi all,
Mhh, strange.
There is a testcase o.a.ojb.broker.AutomaticForeignKeys
that explicitely
tests the assignement of foreign keys for such a 1:n association.
/** test automatic assignment of foreign keys for 1:n
reference. */
GENERAL table'spublic void testOneManyReference() { try { Article art1 = new Article(); art1.setArticleName("TOPLink"); Article art2 = new Article(); art2.setArticleName("OJB"); Article art3 = new Article(); art3.setArticleName("CASTOR"); ProductGroup pg = new ProductGroup(); pg.setName("O/R mapping tools"); pg.add(art1); pg.add(art2); pg.add(art3); Identity pgOID = new Identity(pg, broker); broker.store(pg); broker.clearCache(); InterfaceProductGroup readInPG = (InterfaceProductGroup) broker.getObjectByIdentity(pgOID); assertEquals(pg.getName(), readInPG.getName()); assertEquals(pg.getAllArticles().size(), readInPG.getAllArticles().size()); InterfaceArticle art1a = (InterfaceArticle) pg.getAllArticles().get(0); InterfaceArticle art2a = (InterfaceArticle) pg.getAllArticles().get(1); InterfaceArticle art3a = (InterfaceArticle) pg.getAllArticles().get(2); assertEquals(art1.getArticleName(), art1a.getArticleName()); assertEquals(art2.getArticleName(), art2a.getArticleName()); assertEquals(art3.getArticleName(), art3a.getArticleName()); } catch (Throwable t) { System.out.println(t.getMessage()); t.printStackTrace(); fail(t.getMessage()); } }
Article has a backreference to Productgroup. this testcase passes, so I have no idea what could be wrong here...
cheers, Thomas

I have been having the same issue with 1:n mappings were n's FK is not getting updated if "n" has a reference-descriptor back to "1".

Ahh! That's easy:
WoW! That worked but partially ;-) select * from PARTICLE looks like
id | name | gid ----+----------+----- 3 | AAA | 4 | BBB |
but the gid column is empty. And it has to reference
ID-field.
May be something is wrong with my reference-descriptor for
generalId?
