Adam, As you suggest, creating a named subclass of Label is probably the
best thing for you if you don't want to keep overriding the
getConverter() method.
My 2 cents,

Hi All,
I'm trying to Zen the best solution to my problem and I thought I'd
check with the list to see if anyone else has tackled this.
I have two properties in my business object that are stored as
BigDecimals. One represents money and the other a percentage. I have
registered a BigDecimal converter at the application level but these two
pieces of data should really be formatted differently when displayed in,
say, a list.
I've created two IConverters, MoneyToStringConverter and
PercentToStringConverter, and I have attached them to the Label
components as such:
listItem.add(new Label("surcharge", new Model(project.getSurcharge()))
{
public IConverter getConverter() {
return new MoneyToStringConverter();
}
});
listItem.add(new Label("surchargePercent", new
Model(project.getSurchargePercent())) {
public IConverter getConverter() {
return new PercentToStringConverter();
}
});
And this works. Surcharge is displayed as $50.00 and Surcharge Percent
is displayed as 50.00%. But this seems rather tedious if I have to
attach these to every field that needs conversion for display.
Does anyone have any thoughts on how we could "flag" a field or label
as being a specific semantic type? Should I create a MoneyLabel and a
PercentLabel?
Any ideas would be appreciated!
