Re: textbox showing currency default value
You can add this to your action, locale needs to come from user,
public String getCurrency(float amount) {
Format currencyformat = NumberFormat.getCurrencyInstance(locale);
Return currencyformat.format(amount);
}

Re: textbox showing currency default value
Hi Paolo,
first of all float for cash is a very bad idea. Use BigDecimal.
Then You can ass getter and setter in Form like this:
public String getMyFieldValue() {
return myFieldValue.toString().replaceAll(".", ",");
}
public void setMyFieldValue(String amount) {
myFieldValue = new BigDecimal(amount.replaceAll(",", "."));
}
where myFieldValue is a BigDecimal field in Your form.
You could also use some kind of NumberFormat or something if You like.
Best greetings,
Paweł Wielgus.

Re: textbox showing currency default value
This is my idea: jsp should convert my float value to a String so to display it in my textbox. I suppose jsp uses a subclass of NumberFormat to do so... may I change this behaviour so to use DecimalFormat.getCurrencyFormat()? Thank you in advance...
