I got this error message:
error: Found shared references to a collection: Person.relatedPersons
When I tried to execute addToRelatedPersons(anotherPerson):
person.addToRelatedPersons(anotherPerson);
anotherPerson.addToRelatedPersons(person);
anotherPerson.save();
person.save();
My domain:
Person {
static hasMany = [relatedPersons:Person];
}
any idea why this happens ?
Explanation on practice. If you try to save your object, e.g.:
Set<Folder> folders = message.getFolders();
folders.remove(inputFolder);
folders.add(trashFolder);
message.setFiles(folders);
MESSAGESDAO.getMessageDAO().save(message);
you don't need to set updated object to a parent object:
message.setFiles(folders);
Simple save your parent object like:
Set<Folder> folders = message.getFolders();
folders.remove(inputFolder);
folders.add(trashFolder);
// Not set updated object here
MESSAGESDAO.getMessageDAO().save(message);
