Doesn't show User filed to filter

[LeoStr]

Hi!, can't figured out wy, but filterpane doesn't show duenio field to filter.

This is my domain class:

class Item {
Long id
String nombre
User duenio
String ubicacion
Long cantidad
static constraints = {
}
}

duenio is an instance of User class created with spring security core plugin. ¿Any idea?

It works with associatedProperties on the filterpane tag, but it would be nice if it took the toString () method of the domain class as the default.
