Use collection instead. Internally, castor would use thier lazy loading
collection implementation ( RelationCollection ) during loading but u can
use vector or arraylist for new record creation ( i.e. when the collection
is still null ).

Subject: [castor-dev] lazy loading
I get the below error when I add lazy="true" to many field in castor... Any
help would be appreciated, thanks.
On a related note, is there support for Vector's when using Lazy Loading?
And if not, what does work?
