This happens in FX 11.0.2 and 12. I declare a column for Doubles...
@FXML
private TableColumn<Whatever, Double> myColumn;
When I add this code:
myColumn.setCellFactory(TextFieldTableCell.forTableColumn(new
DoubleStringConverter()));
I get this exception:
Exception in thread "JavaFX Application Thread"
java.lang.ClassCastException: class java.lang.Integer cannot be cast to
class java.lang.Double (java.lang.Integer and java.lang.Double are in
module java.base of loader 'bootstrap')
