I followed the progress of the query in the debugger.
Yes, I'm calling QueryForObject to grab a Customer by ID. Strangely,
the sequence of object construction goes as follows:
1. Creates the Customer
2. Creates the ReferencePeople object
3. Injects a null ReferencePeople object into Customer
4. Creates a Salesman object
5. injects the Salesman into the ReferencePeople object
Despite fully constructing the ReferencePeople object, it injects null
into Customer, unless I add the direct (non "select") attribute to
ReferencePeople.

Do you have logging enabled? Is the sql for GetSalesmanByCustomerID
being executed? I assume you're calling QueryForObject.

Thank you for the quick response.
Yes, I'm using DataMapper 1.5 Beta. The useReflectionOptimizer
setting
was enabled, but disabling it didn't help.

Is useReflectionOptimizer enabled?

I'm having trouble with a resultmapping, using the latest beta of
the
mapper.
The problem occurs when a resultMapping only contains properties
with
select attributes (no direct result properties). In the example
below,
I'm trying to map a ReferencePeople object to my Customer object.
ReferencePeople is a simple class that contains a customer's
reference
people at a company and some minimal logic. As such, it contains
no
properties other than other mapped objects (such as Salesman).
When
doing the mapping below, despite creating ReferencePeople abject
and
adding a salesman to it, Ibatis injects null into the
ReferencePeople
property of Customer. However, if I add any direct property to
ReferencePeople, such as copying the Customer's version property in
there, then Ibatis properly injects a ReferencePeople object into
Customer.
<resultMap id="Customer" class="Customer">
<result property="CustomerID" column="CustomerID"/>
<result property="ReferencePeople"
resultMapping="Customer.ReferencePeopleResult"/>
<result property="Version" column ="Version"/>
</resultMap>
<resultMap id="ReferencePeopleResult" class="ReferencePeople">
<result property="PreferredSalesman" column="PreferredSalesman"
select="GetSalesmanByCustomerID"/>
<!-- If I add a random property from Customer to
ReferencePeople,
so
that it has a direct property, then everything works fine -->
<!--<result property="Version" column ="Version"/>-->
</resultMap>
class customer
properties: CustomerID: long, ReferencePeople: ReferencePeople,
Version: long
class ReferencePeople
properties: PreferredSalesman: Salesman, Version: long (version
was
only added in debugging and does not belong in ReferencePeople)
DB:
Customer and ReferencePeople information are both stored in the
Customer Table, Salesman infromation is in its own table.
Cheers,
