In 1.0 and 1.1-beta-1, there are no standard conversions for BigDecimal.
This has been added in the most recent nightly builds (plus the ability to
register your own custom Converter classes -- see the latest javadocs for
the BeanUtils package <http://jakarta.apache.org/commons/beanutils/api/>).
There is still no standard converter for Date (primarily because you
really need to be locale-sensitive for things like that).
However, using data types like BigDecimal (or Integer, or Date) in your
form beans is not generally a good idea -- you're still going to get
conversion errors if the user types something invalid like "1a3" instead
of "123". You should generally use strings in your form beans, and do the
conversion to your real data types later (in the Action, or via a separate
method like getDatumConverted() in the form bean) after validation has
guaranteed that the conversions will be successful.
