Folgendes Problem tritt
1) Wenn memento zum ersten Mal initialisiert wird der Code ordnungsgemäß funktioniert. Aber wenn ich mein viewPart wieder öffne, ohne irgendwelche Daten zu ändern, tritt der Fehler auf.
2) Ich habe alle meine Werte in hashmap gespeichert. Wenn ich Daten wiederherstelle, bekomme ich nur die ersten 3 Werte, der Rest der Werte erscheint nicht. Wenn ich Zahlen benutze, kommen alle Daten richtig. Irgendwelche Lösungen dafür?
3) In meiner fillTableRoWData() - Methode, wenn die beiden if-Bedingungen ausgeführt werden, stehen alle meine Listener nur unter den zweiten Bedingungen. So verschieben Sie die Listener zwischen zwei Bedingungen.
Hier gibt es viel zu viel Code. Was genau möchten Sie speichern? –
@ greg-449 Ich habe eine Bearbeitung vorgenommen. Ich möchte die Daten speichern, die angezeigt werden, wenn getTable-Methode aufgerufen wird. Wie kann ich es mit der Savestate-Methode speichern? Ich erhalte keine Daten in meinem Viewpart. –
Nun, ist Ihr Code das Speichern in der 'saveState' Methode? Es liegt an Ihnen, diesen Code zu schreiben. –
