Folks,
I have an object; Advertiser that has an object; Account. The advertiser also has an
AdvertiserState object (created on the fly, not in storage) that represents the status
of the advertiser/account combo (the account actually holds the currentStatus as a
string, for persistance. I'm using the persistanceBroker version of OJB. I'd like to
'initialize' the advertiser with it's correct AdvertiserState on creation of the
advertiser-account object.
I note that pb has a class-descriptor attribute: initialization-method:
<class-descriptor
class="com.proj.advertiser.model.Advertiser"
table="ADVERTISER"
initialization-method="init">
.
.
.
<reference-descriptor
name="account"
class-ref="com.proj.account.model.Account"
auto-update="true"
auto-delete="true"
auto-retrieve="true"
>
<foreignkey field-ref="accountId"/>
</reference-descriptor>
... etc />
that can get called on creation. My problem is that the account is created seemingly
after the advertisement, and the whole object is then assembled. Which means that the
account, which has the persistent value of the current object status can't be known
when I want it (when the advertiser's init method would get called) to create my
on-the-fly AdvertiserState association.
Anybody have an idea how I might solve this delemma? Some sort of lazy instatiation?
I'm working around it at present, by creating the whole association and then
programmatically calling an initialization() routine on the created advertiser.
cheers,
hba
