I'm using S2.1.2 (are you using the same version?), and it will throw
a NumberFormatException when setting an empty string, but this
workaround will make ParameterInterceptor to think it is setting a
String parameter:
public void setValue(String s) {
if (!StringUtils.isBlank(s)) {
try {
this.value= new BigDecimal(s);
catch(NumberFormatException e) {
this.value = null;
}
}
}
of course you still need a validator so that the string doesn't
violate the BigDecimal grammar.
Other option (may be more clean) is the action having both the string
instance and the real BigDecimal instance, then the form will only set
the string instance.
