You have to use the TextField constructor that specifies the type of the
model:
https://ci.apache.org/projects/wicket/apidocs/8.x/org/apache/wicket/markup/html/form/TextField.html#TextField-java.lang.String-org.apache.wicket.model.IModel-java.lang.Class-
It should be:
add(new TextField<>("year", LambdaModel.of(obj::getYear, obj::setYear),
Integer.class));
That one always gets me too...
