Hi,

Exception in thread "AWT-EventQueue-0" java.lang.VerifyError: (class:
org/jopendocument/dom/spreadsheet/SpreadSheet, method: move signature:
(Lorg/jopendocument/dom/spreadsheet/Sheet;I)V) Incompatible argument
to function
        at plannos.ExcelFile.rapport1(ExcelFile.java:382)

Code :

String[] columns = new String[] { "BT ", "Ligne ", "Numéro d'OF",
"Article", "Quantité", "Date de début ", "Date de fin " };

          TableModel model = new DefaultTableModel(null, columns);

          SpreadSheet book = SpreadSheet.createEmpty(model);


I use jOpenDocument-1.2b3.jar
