[castor-dev] Why uses castor a long transaction

[Thomas Louis]

Hi,

I've got another Problem. I want to update my products in the Database
like follows:

// unmarshall a list of products from xml
...
// iterate them
while (itor.hasNext()) {
  xmlProduct = (Product)itor.next();
  db.begin();
  db.update(xmlProduct);
  db.commit();
}

Why does castor abort with

java.lang.IllegalArgumentException: A master object that involves in a
long transaction must be a TimeStampable!

I either have any dependent objects nor a long transaction. Wrong?
Product has got Collections of other Objects, but these are not declared
dependent in the mapping file.

Thanks for reply again,
Thomas
