!MESSAGE c.s.f.LifecycleManager.saveDialogSettings:451|Can't save dialog settings. Reason: Illegal character in path at index 54: file:/home/user/Fakturama Betrieb1/.metadata/.plugins/com.sebulli.fakturama.rcp

Hier das Log vom betreffenden Zeitpunkt. Wobei anscheinend ein weiterer Fehler, der sich bisher nicht bemerkbar gemacht hat geloggt wird: Es dürfen keine Leerzeichen im Pfad des Arbeitsverzeichnisses sein?

Das mit den Leerzeichen ist mit auch neu, da hab ich nicht dran gedacht. Bei Windows ist das ja kein Problem. Der andere Fehler betrifft einen Rabatt, der da nicht ausgewertet werden kann (also in einem Feld für den Rabatt steht nichts, obwohl da was erwartet wird). Ich seh mir das mal eben an.

Nachtrag: Das mit dem Rabatt ist tatsächlich ein Fehler. Der tritt aber nur bei den Rechnungskorrekturen auf. Den anderen Fehler mit dem Leerzeichen bekomme ich nicht so schnell hin, das hängt halt immer vom Betriebssystem ab. Theoretisch kann Linux auch mit Leerzeichen im Dateiname umgehen. Danke nochmal für den Tip.
