For example, if enter 'abc' into a BigDecimal' then the error message returned is effectively hardcoded because in IsisWicketApplication we just use Wicket's default ConverterLocator (fine tuned with a couple of extra types to convert). That means we get:
We also have a bit of technical debt, because there is an IsisConverterLocator that doesn't implement Wicket's IConvertLocator, and is just called from one place, statically, to render an object as a string.
So we should perhaps:
- provide our own impl of IConveterLocator, probably subclassed from Wicket's
- make it a Spring Bean
- get rid of IsisConverterLocator (roll it into aforementioned IConverterLocator)
- decide on a way to allow new/replacement converters to be registered.
We might also want to look at the ValueTypeRegistry we have, just in case there's overlap.
