I need to provide some background: I have a web app (Spring+Cayenne)
which has been modularized so that functionality can be added or removed
w/ as little effort as possible.
Lets say for example, that I have a module called core that has an
address table which I would like to make available to all the other
modules but I don't want the address table or its domain object to know
anything about the other modules. So here is the address table ...
Address
------------------------
adress_id
street_1
street_2
city
state
postal_code
country
... and here is a table in another module that would like to use the
"core" Address functionality ...
Customer
-----------------------
customer_id
first_name
last_name
...
shipping_address_id
billing_address_is
So that I don't have a dependency from the core module you can see that
the relationship will only be one way from customerToAddress.
(address.address_id -> customer.shipping_address_id, etc). I don't want
the reverse relationship b/c then there will be a reference (in the
mapping xml) from core to an addon module.
This seems to work OK when I store the object. The
customer.shipping_address_id (and billing_address_id) fields are
populated in the database. However, when I try to access the billing
address (via customer.getCustomerToBillingAddress()) method, an address
object is returned, however, all the values are null. I'm wondering if
this due to the lack of a reverse relationship?
TIA
