hasMany mapping for 'eager' only returns first result when using findBy* gorm method

I have a one to many association mapped as:
class Site {
static hasMany = [subItems:SubItem]

static fetchMode = [subItems: 'eager'] // not working in grails 2.0.1, 2.0.2

static mapping =

}

class SubItem {
String mkey
String mvalue

static belongsTo = [site:Site]

static constraints =

static mapping =

}

performing:
Site.findById(1)

correctly returns site #1, but if site #1 has more than one subItem... only the first subItem is returned (using the fetchMode designation). If you remove fetchMode the items are fetched lazily with a subsequent query and all values are found.

Seems due to the fact that the query being executed has a 'limit 1' at the end thereby returning only the first sub-item in the result-set rather than all sub items.
