Description:
If DataObject's validateForSave indirectly modifies ObjectStore, a ConcurrentModificationException is thrown:
http://objectstyle.org/cayenne/lists/cayenne-user/2004/06/0092.html
Test DataObject that shows how to reproduce the problem:
class MockupActiveValidatingObject extends CayenneDataObject {
public void validateForSave(ValidationResult validationResult) {
// create a new object on validation... this will end up in the ObjectStore
// so lets see how the ObjectStore can handle this operation during
// validation....
getDataContext().createAndRegisterNewObject(Artist.class);
}
}
