Nic,
I had the same problem with the IndexOutOfBoundsException.
I fixed the demo code to get it working with the gen2 package:
public void onModuleLoad() {
int numStudents = 100;
...
FixedWidthGrid dataTable = createDataTable(numStudents, 10);
./.
/**
* Create the data table.
*
* @return a data table
*/
private FixedWidthGrid createDataTable(int rows, int cols) {
// Create a new table
FixedWidthGrid dataTable = new FixedWidthGrid(rows, cols);
// Set some options in the data table
dataTable.setSelectionPolicy
(SelectionGrid.SelectionPolicy.MULTI_ROW);
// Return the data table
return dataTable;
}
Best Regards,
Johan Vermeire
