Beware that If you are using the connector.js, dataparocessor will send its value by POST ( so it will be $_POST["!nativeeditor_status"] )
Also, if you are using send-all-at-once behavior , there will be multiple statuses in the POST (GET), and param name will be $POST["{id}!nativeeditor_status"]
Version 2.0 may provide empty value of !nativeeditor_status for update operations ( was fixed in later versions), but still parameter itself must exist
