All Implemented Interfaces:

RelationMergeHandler

@Component
public class UserUserRelationMergeHandler
extends AbstractAddressAddressAndUserUserRelationMergeHandler

Custom

invalid reference

RelationMergeHandler

for User→User_user relations. This handler removes potential duplicates if multiple source users have a relation to the same user. This is necessary to avoid a validation error (see

invalid reference

EqualUserUserEntityExistsValidator

). If there are duplicates it is important to remove the 'new' value and keep the existing one, because the validator uses a query to compare uniqueness.
