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.
