I do something like this:
public static <T> T as(Class<T> type, Object value) {
if (type.isInstance(value)) { return type.cast(value); }
return null;
}
public Fruit getFruit() { return as(Fruit.class, article); }
public Vegetable getVegetable { return as(Vegetable.class, article); }
In your template you can then use <t:if test="fruit"> ... </t:if>
