ISimpleTypeModifiable. UnsupportedOperationException on setLocale method

Question

Hi,
I have some context attribute(build in decimal type), and want to configure output view(grouping and decimal separators) of this value on UI components for different users using  ISimpleTypeModifiable interface. I didn't find any setter methods for Formatter(NumberFormat interface). So, I have tried to use setLocale method(different locales have different separators: "RU" locale output for ex. - 123 456,78), but it throws UnsupportedOperationException. Here is some simple code to describe this situation:
ISimpleTypeModifiable type = attrInfo.getModifiableSimpleType();
type.setLocale(new Locale("some locale"));
type.setFormat("some format");
If there is some other way to configure output view for decimal attributes without changing attribute type?
Thanks

Hi, Mikhail!
The simplest solution is to configure (or change in runtime - if it possible) user's locale.
Also you can create calculated read only attribute of type string and use it for presenting your decimal value in right format. Something like this:
// get method of calculated attribute
final NumberFormat format = NumberFormat.getInstance(locale);
return format.format(numericValue);
More one solution is creating "right localized" attribute dynamically:
final ISimpleType decimalType = attrInfo.getSimpleType(); // some decimal attribute created in designer
final ISimpleTypeModifiable localizedDecimal = decimalType.cloneType(locale);
localizedDecimal.setFormat("some format"); // specify format if need
nodeInfo.addAttribute("DecimalValue", localizedDecimal);
