Seltsamer Bug bei Wertänderung eines Landes mit anschließendem speichern. #1

Open AceVanCleef opened 7 years ago

AceVanCleef commented 7 years ago

Guten Abend Herr @DieterHolz

Die Integration unseres cuie custom controls funktioniert soweit gut. Ebenfalls konnte ich gemäss Ihrem Vorschlag das äussere /libs entfernen.

Doch wenn man die Applikation nun startet und dann z.B. den Namen eines Landes verändert und dann gespeichert wird, lässt sich die Applikation nicht mehr neu starten. Wie im nachfolgenden Video gezeigt lässt sich dieser Fehler wunderbar reproduzieren.

Hinweis: In der Beschreibung finden Sie die Erläuterungen zu den von mir gezeigten Schritten im Video, inkl. Zeitsprungmarken. https://www.youtube.com/watch?v=asnRWy_j1y8&feature=youtu.be

Zur Einfachheit hier der Stacktrace und die Rebuildwarnungen zum nachlesen:

Mein Gesamteindruck ist wie folgt: 

allCountries.addAll(service.findAll().stream()
                .map(dto -> new CountryPM(dto))         //Mapping von DTOs zu PMs
                .collect(Collectors.toList()));         //Alle PMs zur ObservableList

Was ist Ihr Eindruck, wodurch das Problem ausgelöst werden könnte?

Freundliche Grüsse, Stefan W.

Das Problem sieht man am Ende des gespeicherten Files. Da stehen noch Zeichen drin, die dort nix zu suchen haben.

Mit Files.write(getPath(FILE_NAME), dtosAsString, StandardCharsets.UTF_8, StandardOpenOption.WRITE, StandardOpenOption.TRUNCATE_EXISTING);

sollte es besser gehen.
