I'm back.
I created object attributes for 3 foreign keys. Example for one of them:
public void setStreetId(Integer streetId) {
writeProperty("streetId", streetId);
}
public Integer getStreetId() {
return (Integer)readProperty("streetId");
}
and now instead of setting the relationship:
houseNumber.setStreet(localStreet);
I do:
houseNumber.setStreetId(streetMid);
But now I am getting
Validation failure for com.acme.maps.model.HouseNumber.street: "street" is
required.
Nowhere in the mapping file or in the modeler there is an option to set the
optionality of the relationship, only for attributes. Why am I getting this
validation message?
At the database level, the FK attribute is set to "NOT NULL", but this is
not related with the Cayenne.
Hints?
