Change a standard Warning message

Question

Hello all,
Here is my issue :
I'm using a type BigDecimal which is formated like this : 0.# so as to not allow the use of the " , " as a decimal separator.
Actually when a user use this " , " there is a warning message which is :
"Enter the value in the format -2733.3"
And I'd like to have a warning message such as : "Please use a number between 0 and 99.9"
I know I have to add a part of code to realize my own check but I don't know exactly how.
Thank you for your answer and your help.
Warm Regards

One dificult solution its that you make those elements Strings instead of BigDecimal.
then youll have to check whether or not the String its a propper Decimal. You could do that making your own definition using the String.match(). If its not what you want then you put your custom message.
Or you can use the libraries that ninit gave you for validation
public BigDecimal validate(String value, Locale locale)
Validate/convert a BigDecimal using the specified Locale.
Parameters:
value - The value validation is being performed on.
locale - The locale to use for the number format, system default if null.
Returns:
The parsed BigDecimal if valid or null if invalid.
After you check if it is a propper Decimal you have to convert the String to BigDecimal.
Its really nasty doing this ...
Also when you show the BigDecimal values, that must be for a currency, you have to change the . for , and viceversa so you have to use a String type again with a replace function or the java.util.Currency class
Another solutions are wellcome
