4.5.4.2.1. Standard Actions over Collection

setAutocommit() allows you to control the moment of entity removal from the database. By default commit() method is invoked after triggering the action and removing the entity from the data source. As result, the entity is removed from the database. You can set autocommit property into false using setAutocommit() method or corresponding parameter of the constructor. In this case you will need to explicitly invoke the data source commit() method to confirm the removal after removing the entity from the data source.

The value of autocommit does not affect datasources in the Datasource.CommitMode.PARENT mode, i.e. the datasources that provide composite entities editing.

setConfirmationMessage() allows you to set message text for the removal confirmation dialog.

setConfirmationTitle() allows you to set removal confirmation dialog title.

afterRemove() is invoked by the action after the entity has been successfully removed. This method does not have implementation and can be overridden.

setAfterRemoveHandler() allows you to provide a handler which will be called after the new entity has been successfully removed. This handler can be used instead of overriding afterRemove() to avoid creating the action subclass. For example:

@Named("customersTable.remove")
private RemoveAction customersTableRemove;

@Override
public void init(Map<String, Object> params) {
    customersTableRemove.setAfterRemoveHandler(new RemoveAction.AfterRemoveHandler() {
        @Override
        public void handle(Set removedItems) {
            showNotification("Removed", NotificationType.HUMANIZED);
        }
    });
}
