In my case I didn't care what the ID generator was (using the default long). It wouldn't load the object no matter what method I tried, at least not directly. I would have to do something like company.employees[0] to get the employee reference back. More of an annoyance than anything else.

def company = builder.company( name: ‘ACME’ ) {
address( id: ‘a1′, line1: ‘123 Groovy Rd’, zip: 12345, state: ‘JV’ )
employee( name: ‘Duke’, employeeId: 1 ){
address( refId: ‘a1′ )
}
}

Calling something like Employee.findByEmail('blah') would return null, even that I added them.
