Ich habe eine Problem mit dem binden von Entities mit einer BeanFieldgroup.
Sobald ein User auf Speichern drückt, wird der binder comitted. Bei einem Fehler erscheint eine Exception.
Das Problem ist, dass der binder nicht alle Felder/Atribute zurückrollt/Rollback, sondern nur die die Fehlgeschlagen sind.
Beim erneute speichern bindet der binder aber wieder alle Felder/Attribute. Ein Object z.B aus einer ComboBox, das im Backend in eine Liste gepackt wird ist somit zweimal enthalten.
wie kann ich dem Binder sagen das er alle felder zurückrollen soll?
Hast du schon versucht, deine FieldGroup mit setBuffered(true) transaktional zu machen? Dann werden die Daten erst nach erfolgreichem Commit in das Item geschrieben.
ja, die FieldGorup ist buffered. Die Daten werden zwar erst mit dem commit in das Item geschrieben aber wenn erst das letzte Feld eine Exception meldet, sind trotzdem alle Daten im Item gespeichert und nur das letzte Feld bzw. der letze versuch ein wert ins Item zu schreiben wird rückgängig gemacht.
