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!
