Re: [eclipselink-users] EclipseLink LAZY fetching without weaving

[Tom Ware <tom.ware@xxxxxxxxxx>]

The first thing to keep in mind is that weaving is only used for LAZY loading of 
xToOne relationships, so you will get lazy Functionality on xToMany 
relationships without weaving.

The other option for weaving of xToOne relationships is to write classes that 
explicitly contain instances of EclipseLink ValueHolder object to represent 
xToOne relationships.

We have not yet heard a compelling reason to implement a dynamic subclassing 
strategy in addition to our weaving strategy and I am curious to know what 
constraints you have the prevent static weaving but allow dynamic subclassing. 
Could you provide some more information?
