I having a query on a table that maps to another
table as a lookup. One of these fields always returns null ;although all the
other fields are properly populated from the table. When I update data in the
main table the null is then written back and I loose my actual data!
Has anyone seen

Alright, alright... I'll skip the pluggable lock engine. If I'm the

My vote, if I have one, is for performance optimization on the 1 to many,

Hi Kate,
You can't do that directly through the Marshaller API but you can do it
by instantiating your own serializer, setting the indent property and
then pass it to the Marshaller.

Is there a way to programmatically turn indenting on/off
before a marshall() ? I don't see any obvious API access
through Marshaller, or other classes in castor.xml.

I can agree that simple replacement of the LRU isn't all that is
needed... and that 'removal' of objects is more of a suggestion to the
LRU than a demand due to locking. Furthermore, I do also agree that
