Re: TextFieldInteger
I just whipped up a test, this is working - at least on 1.4.1 FormVoid form = new FormVoid(form); add(form); final TextFieldInteger textInt = new TextFieldInteger(textInt, new ModelInteger()); textInt.setType(Integer.class); form.add(textInt); I did not get any errors casting to Long. I even added a feedback panel and put in alpha characters. It properly came back stated that ...'abc' is not a valid Integer.

Re: TextFieldInteger
If I take out the setType method, still no cast error, but the Integer checking is not done - feedback panel does not receive an error.

Re: TextFieldInteger
impossible
there is so such thing as ParameterizedType for the example you give..
if you do:
TextFieldInteger field = new TextFieldInteger();
then at runtime that information isnt there anymore. Its gone. welcome
to type erasure..
I think stuff like that is only there if you do:
class MyTextField extends TextFieldInteger
{
}
but then you can already do that just fine in the constructor
yourself.. (calling setType))

So maybe it's a good idea to make it automatic on the framework,
On all TextFieldE constructors without the type parameter we should call
setType() like this:
setType((Class?) ((ParameterizedType)
getClass().getGenericSuperclass()).getActualTypeArguments()[0]);
Too complicated??
