Re: Mapping question

I now have a running version, but the way Thomas proposed would be much 
nicer.

I have added a collection descriptor

  

and he returns both addresses.
I tried to modify my getters and setters for addresses to set 
homeAddress and workAddress, but I tested this and noticed that they are 
not invoked (why should they? (*grml*))

So I added a function assignAddresses(), which is invoked by the DAO 
getUser method.

public void addressAssignment() {

  Iterator i = this.adresses.iterator();
  while (i.hasNext()) {
Adress address = (Address) i.next();
if ("home".equals(adress.getType()))
  this.homeAddress = address;
if ("work".equals(adress.getType()))
  this.workAddress = address;
  }
}
Now I have to take care that every setHomeAddress also modifies the 
collection (because I don't think that getAddresses() is invoked by ojb 
either ;) )

May be I implement a query costomizer who filters the addresses like 
described in the advanced mapping tutorial:

Yes, that is what I am searching for.

Sorry for that second posting. I sent this before I subscribed to the 
list, so I thought it will not be posted (now, with a latency of nearly 
one day)

Mapping question

[Georg Müller]

Hi,
I have an object "User" who has 2 addresses, home and work.
User is mapped to a table user (no problem here).
Both home and work address are mapped to a table address.
This table has a composite primary key: login and type
 - login from table user as a foreign key
 - type is a string (or enum) "home" and "work"
I have tried the following without success:
in User description:

  
  

and in Address description:


Is it possible to make it run anyhow?
Regards,
Georg
