Martin Grigorov commented on WICKET-3385:
-----------------------------------------
You know that Java (and Scala) use type erasure and this 'C' is lost at runtime.
Give it a try locally and see what happens.
ConvertersTest will show you all class casts.

> Components: wicket
> Affects Versions: 1.5-RC1
> Environment: all
> Reporter: Richard Emberson
> Assignee: Martin Grigorov
> Priority: Trivial

> if
> BigDecimalConverter parametrizes AbstractDecimalConverter with BigDecimal
> then
> AbstractDecimalConverter parametrizes AbstractNumberConverter with BigDecimal
> and then
> AbstractNumberConverter parametrizes AbstractConverter with BigDecimal
> which means that AbstractNumberConverter parse method returns a BigDecimal
> so that in BigDecimalConverter convertToObject method
> the line:
> final Number number = parse(value, -Double.MAX_VALUE, Double.MAX_VALUE,
> locale);
> should be:
> final BigDecimal bigDecimal = parse(value, -Double.MAX_VALUE,
> Double.MAX_VALUE, locale);
> and all the code that follows that line can be replaced with:
> return bigDecimal;
