Grails - fetchmode - what's it do?

Question

In my Grails domain I have something like the following

class A {
    String name
    static hasMany = [ b : B ]
    SortedSet b
    static fetchMode = [ b:"eager" ]
}

class B implements Comparable{
    A a
    ... compareTo method defined ....
}

What I'm trying to do is to retrieve an instance of class A, and at the same time have its collection (b) populated.

So I do A.get(1), expecting b to be populated,

but b.each(){ println it }

tells me that I'm calling each on a null object

I fear that I am fundamentally missing the point here, but I can't see what I'm doing wrong.

I'm running this as as integration test, against a MySql database. The database appears to be populated with data that would allow the association between A and B.

Any help greatly appreciated.

Maybe you need

static mapping = {
b lazy:false }
