Some thoughts...
JBoss CMP has a neato feature called load groups.
I have an Item class that has nearly 70 attributes. Many attributes are related. For example, length width height weight diameter are all nicely kept in a Dimensions component - but are rarely ever used in use cases. Even worse, I have fields such as "Description" and "Notes" that could be very large CLOB fields.
Certainly - some attributes such as Title, Number, Price are needed in many many other use cases. Showing the user a list of 100 items I wish could be fast with little memory requirements. I would like, therefor, at least to have components mimic JBoss load groups.
Otherwise - I am looking with creating multiple "Views" (persistent objects - polymorphism is just not a proper approach) onto the same tables - although this will no doubt hose the default JCS cache.
THANKS!!

Description:
Lazy loading for components
Could I throw a request on to allow for lazy loading of
components? If I had a class, Person, that had a
component, Address, I'd love to be able to load Person
without having to load Address. This would be akin to
JBossCMP's load groups.
