JTable speichern, Fehler bei Selection

[FaxXer]

Hallo,
ich habe das Problem, dass wenn in meiner Tabelle etwas markiert ist und ich sie dann abspeichern will nichts mehr Funktioniert bzw viele Fehlermeldungen erscheinen.

Natürlich hab ich auch schon gegooglet und anscheinend ist dieses Problem bekannt und es wurde geraten die Markierungen vor dem speichern zu entfernen. Genau das hab ich versucht allerdings bekomme ich immer noch Fehler, allerdings andere. Wäre nett wenn ihr mal drüber schauen könntet.

Du kannst JTable nicht in einen Stream geben, deshalb die Exception.

Hä wie was meinst du? Ich schreibe das tableModel in eine Datei klar geht dass. Funktioniert ja auch solange man keine zeile in der Tabelle markiert und dann speichert.
Ich verstehe jetzt nur nicht warum clearSelection einen Fehler wirft..

Schau mal hier:
http://www.java-forum.org/allgemeine-java-themen/76357-defaulttablemodel-wirft-beim-serialisieren-exception.html
Hab ich gerade beim googlen gefunden. Vielleicht hilft dir das ja weiter. Ich würde aber auch nur die Daten speichern und nicht das TableModel versuchen zu serialisieren...
