N+1 select and groupBy

[Mark Volkmann]

I've got a simple situation where Store objects have a property that  
is a collection of Phone objects. I've read the section in the iBATIS  
documentation and the book that discusses how to setup this kind of  
mapping using the resultMap groupBy attribute. My select takes a  
storeID, so I expect to get back one Store object that holds a  
collection of Phone objects. The actual store in my test has two  
phones. What I'm getting back is two Store objects that each have one  
Phone.

I can provide more detail, but I thought I'd start with just this and  
see if anyone has a guess as to what I might be doing wrong. Perhaps  
you've hit this problem too and solved it.
