I hate repeating myself and being the compiler's teacher. IMHO the
generics that are implemented in Java resulted in terrible code where
you have to repeat yourself over and over and over. Are you sure your
text field holds a String and your model returns a String?
TextField<String> field = new TextField<String>("someId", new
PropertyModel<String>(foo, "property"));
This counts for 3 times the type String. In a recent discussion with
Igor on ##wicket, we saw a way to remove at least 1 String. By
providing model factory methods for concrete models: Model,
CompoundPropertyModel and PropertyModel. For abstract models it
doesn't make sense...
Igor suggested the following syntax:
TextField<String> field = new TextField<String>("someId",
PropertyModel.of(foo, "property"));
i.e. ModelType.of(....)
I am +1 for adding these methods.
We can do the same for components, although the benefit is typically
less, and it might even send our users down the wrong path thinking
they can't use the 'new' keyword.
TextField<String> field = TextField.of("someId", PropertyModel.of(foo,
"property"));
WDYT?
