In FormComponent class
/**
* subclasses would override it instead of getConverter(Class)
so no cast is necessary
*/
public IConverterT getFCConverter(ClassTtype)
{
// -- returns converter for FormComponent's type
return super.getConverter(type);
why getFCConverter would need a Class as parameter?
I mean, FormComponent whould be already known whether by getType or by
T type... wouldn't it?

i think it would need class because getConverter itself needs class
gettype() resolves class from the class name afaik ..

do you mean something like ( in FormComponent class or one subclass ) :
/**

protected IConverterT getConverter()

Hello everybody,
I'm using wicket 1.5-RC5.1 and I'm having problem to override
getConverter method of in a FormCompont subclass.
Well, lets say I have a TextFieldDate (I'm using j.u.Date here just
as example, could be any type) when I try to to provide a specific
converter for my instance I

Hello Martin, thanks for you prompt response..
I had saw that solution but it uses an unchecked cast that was
exactly what I was trying to avoid.
I guess generics were introduced just to avoid those types of casts.

heheh ... well, in my opinion the best solution is to change
definition of Component.getConverter in way its generic type is bound
to FormComponent's T generic type ...
Is there any change to have it changed?

Try it.
The problem is that getConverter(Class) is defined in Component which
has no type parametrization.
FormComponent extends Component and has the type but cannot break the
signature...

^^ means not overriding correctly as method signature is not the same

The real problem is that Component has no generics.
The tradeoff is that the library (FormComponents) do cast but all
users of them benefit without seeing this casting

i agree with that so type parameter has to be used on the method
currently unless a new method is added in the FormComponent ,the older
method can just call the new method based on some conditional logic so
nothings get broken in core..,the users
sorry i just realized i goofed up while copying the method signature ..
there is no final in the method signature..
