Hello everybody,
Seems like the class attribute "depends" doesn't work w/ long
transaction.
code snippet (derived from the JDO example of Castor)
in mapping.xml
...
<class name="net.uniopt.jdo.example1.ProductDetail"
identity="id"
depends="net.uniopt.jdo.example1.Product">
...
</class>
...
in Main.java
public
void run(PrintWriter writer) throws Exception {
Database db;
Product product=null;
ProductDetail detail = null;
db = _jdo.getDatabase();
// TA -1- //
db.begin();
product = (Product)db.load(Product.class, new Integer(4));
if (product == null) return;
product.setName("XXX");
detail = new ProductDetail();
detail.setName("aaa");
detail.setId(product.getId()*10 + 1);
product.addDetail(detail);
db.commit();
// TA -2- //
db.begin();
db.update(product); //-1-//
product.setName("YYY");
detail.setName("bbb");
db.commit();
db.close();
writer.println("Test complete");
}
When I run the example I get the exception
[test] org.exolab.castor.jdo.DuplicateIdentityException: update object which is already in the transaction
[test] org.exolab.castor.jdo.DuplicateIdentityException: update object which is already in the transaction
at //-1-//
but only if there's already one or more entries in the details table. If its empty the example works successfully.
Any hints or do I have to bugzilla.
Regards,
Michael
