Jochen Kemnade closed TAP5-1947.
--------------------------------
Resolution: Incomplete
We assume this is no longer relevant and therefore close it.
If you still have this issue in a recent Tapestry version (such as 5.4.1 or
newer), feel free to provide the necessary information and reopen.

> Tapestry should offer the ability to validate BigDecimal max length's for
> currency/amounts. I'm donating the following code which validates maxScale
> and maxPrecision. Unfortunately, I haven't written anything to handle the
> clientside validation.
> //app.properties
> maximum-precision=You may provide at most %d numbers for %s.
> maximum-scale=You may provide at most %d decimal digits for %s.
> //MaxScale
> public class MaxScale extends AbstractValidator<Integer, BigDecimal> {
> public MaxScale() {
> super(Integer.class, BigDecimal.class, "maximum-scale");
> }
> @Override
> public void validate(Field field, Integer constraintValue,
> MessageFormatter formatter, BigDecimal value)
> throws ValidationException
> {
> if (value.scale() > constraintValue)
> throw new ValidationException(buildMessage(formatter, field,
> constraintValue));
> }
> private String buildMessage(MessageFormatter formatter, Field field,
> Integer constraintValue) {
> return formatter.format(constraintValue, field.getLabel());
> }
>
> @Override
> public void render(Field field, Integer constraintValue, MessageFormatter
> formatter, MarkupWriter writer,
> FormSupport formSupport) {
> formSupport.addValidation(field, "maxscale", buildMessage(formatter,
> field, constraintValue), constraintValue);
> }
> }
> //MaxPrecision
> public class MaxPrecision extends AbstractValidator<Integer, BigDecimal> {
> public MaxPrecision() {
> super(Integer.class, BigDecimal.class, "maximum-precision");
> }
> @Override
> public void validate(Field field, Integer constraintValue,
> MessageFormatter formatter, BigDecimal value)
> throws ValidationException
> {
> if (value.precision() > constraintValue)
> throw new ValidationException(buildMessage(formatter, field,
> constraintValue));
> }
> private String buildMessage(MessageFormatter formatter, Field field,
> Integer constraintValue) {
> return formatter.format(constraintValue, field.getLabel());
> }

> formatter, MarkupWriter writer,
