is it an enhancement?

CK>I want to describe the issue as following (derived from the LazyLoading testcase):

CK>I have a Person that has Addresses.
CK>Assume that s/he has more than 1000 addresses.
CK>I want to get only those for a specific zip code without loading them all with
person.getAddress() and

CK>I loaded a TestLazyPerson object before as aPerson.
CK>Now Id like to run the following query:
CK>query = _db.getOQLQuery("SELECT a FROM jdo.TestLazyAddress a " +
CK>"WHERE Person = $1 AND zip = $2");
CK>query.bind( aPerson );
CK>query.bind( "10000" );
CK>
CK>I get error messages both for TestLazyPerson having a single identity or multiple
PKs! .
CK>
CK>I read a little bit through the source code and it seems for me that this is not
implemented yet.
CK>Mainly in the ParseTreeWalker and in OQLQueryImpl there would be some changes
necessary.

CK>My first question:
CK>Am I completely wrong to try such a query? Could somebody tell me how to solve this
better in this case.

CK>The 2nd question (if you are still with me):
CK>Are there plans to implement this functionality in the near future anyway or
otherwise Id like to
CK>volunteer to add/change this.
CK>Who are the contacts to discuss this in further detail?

CK>I attach a Testcase that shows what I mean
Clemens,
This feature has been requested in the past and is something we're hoping
to address with some major refactoring in the future. At this time,
the only way to get an Address object without fetching all of them is
to query the Address separate from the Person.
