Hello all,
Thanks for your support.
It was quite some work, but I managed to get it working..
For everybody else who is struggling with this, here is my code for Tapestry
5.2.6
----Page.tml
<input type="text" t:type="textfield" t:id="currencyInput"
t:validate="required" value="price" translate="currency" />
----CurrencyTranslator.java
import java.text.DecimalFormat;
import org.apache.tapestry5.Field;
import org.apache.tapestry5.MarkupWriter;
import org.apache.tapestry5.ValidationException;
import org.apache.tapestry5.internal.translator.AbstractTranslator;
import org.apache.tapestry5.services.FormSupport;
public class CurrencyTranslator extends AbstractTranslator<Double> {
private static DecimalFormat decimalFormat = new
DecimalFormat("0.0000");
public CurrencyTranslator() {
super("currency", Double.class, "currency-format-exception");
}
@Override
public String toClient(Double value) {
return decimalFormat.format(value);
}
@Override
public Double parseClient(Field field, String clientValue, String
message) throws ValidationException {
Double returnValue = null;
if(clientValue != null) {
try{
returnValue = Double.valueOf(clientValue);
}
catch(Exception e) {
throw new ValidationException(message);
}
}
return returnValue;
}
@Override
public void render(Field field, String message, MarkupWriter writer,
FormSupport formSupport) {
}
}
----AppModule.java
public static void contributeTranslatorSource(MappedConfiguration<Class,
Translator> configuration) {
configuration.override(Double.class, new CurrencyTranslator());
}
