In Vaadin 7 i was using Field Super Class to get the TexField, DateField Object Value.
Now the Field Class is not present in Vaadin8, what can i do to get the value of some different fields type without refer to them with them Class but with a super class that is trasversal to them ?
Map<String, Object> fieldMap = new HashMap<String, Object>();
TextField tf = new TextField();tf.setValue("Test");
Field field = fieldMap.gett("testField1");
Object value = field.getValue();
