I tried the following syntax as documented at http://grails.org/doc/1.0.x/guide/5.%20Object%20Relational%20Mapping%20(GORM).html#5.5.1%20Events%20and%20Auto%20Timestamping
Example C

class Face {
Nose nose
}
class Nose { // Missing def face static belongsTo = [face:Face] }

and I get this error:

I changed the syntax to:

static belongsTo = Face

as indicated a bit further down:

You could keep the previous relationship as unidirectional and allow saves/updates to cascade down by doing the following:

class Face {
Nose nose
}
class Nose {
static belongsTo = Face

}

and everything runs fine.

It seems that I needed

def face

to be able to use the

static belongsTo= [face: Face]

syntax

Without the "def face" I need to use "belongsTo: Face"
