NumberFormatter
I have a TextField that shows a double value. But I want to format the value in the Textfield as a decimal with 4 decimals (i.e. 0.1234) In Tapestry there is a NumericFormatter and a BigDecimalNumericFormatter. But I can't find any documentation on how to use these on a TextField. Can someone give me an example how I can format my double value into a decimal value with 4 decimals? regards, Leon - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Re: NumberFormatter
Hello Chris, Thank you. Yes I have already seen that page, but I couldn't find an example with a FieldTranslator.

Re: NumberFormatter
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 AbstractTranslatorDouble {
private static DecimalFormat decimalFormat = new
DecimalFormat(0.);
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(MappedConfigurationClass,
Translator configuration) {
configuration.override(Double.class, new CurrencyTranslator());
}

For input fields (such as TextField) you can add a parameter translate
of
type FieldTranslator which translates between the object (e.g.
BigDecimal)
and the String representation in the input.
See:
http://tapestry.apache.org/current/tapestry-core/ref/org/apache/tapestry5/corelib/components/TextField.html
You can also define your translator globally by contributing to
TranslatorSource.
