------------------------------------
Fix Version/s: 8.0.0-M1
> Reconsider generics of IConverterLocator#getConverter()
> -------------------------------------------------------
>
> Key: WICKET-5866
> URL: https://issues.apache.org/jira/browse/WICKET-5866
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Affects Versions: 7.0.0
> Reporter: Sven Meier
> Assignee: Sven Meier
> Priority: Minor
> Fix For: 8.0.0-M1
>
>
> IConverterLocator#getConverter() has a generic parameter <C> currently.
> It seems to me that this is not very useful: almost all code calling
> #getConverter() does not care for the type parameter.
> From the user perspective it's very common to override
> Component#getConverter(). With the need for a cast and to suppress the
> generics warning, providing a custom converter is much too hard currently:
> {code}
> public <C> IConverter<C> getConverter(Class<C> clazz)
> {
> if (Date.class.isAssignableFrom(clazz))
> {
> @SuppressWarnings("unchecked")
> IConverter<C> result = (IConverter<C>)converter;
> return result;
> }
> else
> {
> return super.getConverter(clazz);
> }
> }
> {code}
> I propose to remove the generics parameter from the method.
