Record Objects generated with complexModel = true will include the get all associated FK records methods, e.g.
List books = author.getBooks()
regardless of the objectIsCaching setting.
Beans however, will NOT generate the get associated FK records methods unless objectIsCaching is true.
FWIW, the get related PK object methods are generated, e.g.
Author a = book.getAuthor();
regardless of objectIsCaching.
The Bean template coding needs to be reviewed and fixed to generate code correctly.
