Werner,
I have two different mappings.
It's the problem with XML transient field and not JDO. The JDO part seems to
work fine.
I would like to here from Keith.
Here's a pseudo code and explanation:
1. products have items field. in JDO Mapping items are marked as lazy-loaded
for products.
In the XML mapping file, I have this items field of products marked as
transient.
when i try to do this:
product = db.load(...);
marshaller.marshall(product);
I got exception that trans is not in progress - this is because lazy-loading
implementation (this Relational collection or whatever) doesn't allow us to
iterate lazy-loaded fields out of transaction.
Now, if I do this:
product = db.load(...);
product.setItems(null);
marshaller.marshall(product);
everything works fine.
Later I can write a unit-test and submit a report to buzilla. I'm almost sure
that this is a bug on XML side, just want to here from Keith.
Regards,
Emir
