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

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());
}

When you need to "contribute" a configuration or anything to tapestry, first
check this page:
http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/TapestryModule.html
Find the method likely to satisfy your need, like in your case here:
http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/TapestryModule.html#contributeTranslatorSource(org.apache.tapestry5.ioc.MappedConfiguration,
org.apache.tapestry5.internal.translator.NumericTranslatorSupport)

Hello Chris,
Thank you. Yes I have already seen that page, but I couldn't find an example with a FieldTranslator.
Does anyone have an example how to do this?
regards,
Leon

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.
