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
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 {
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(MappedConfiguration configuration) {
configuration.override(Double.class, new CurrencyTranslator());
}

Re: NumberFormatter
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) Google it to see it in action: http://www.google.com.eg/search?gcx=w&sourceid=chrome&ie=UTF-8&q=contributeTranslatorSource#sclient=psy-ab&hl=en&source=hp&q=tapestry+%22contributeTranslatorSource%22&pbx=1&oq=tapestry+%22contributeTranslatorSource%22&aq=f&aqi=&aql=&gs_sm=e&gs_upl=13088l14418l1l14680l2l3l0l0l0l0l0l0ll1l0&bav=on.2,or.r_gc.r_pw.,cf.osb&fp=127c72f3b5eca502&biw=1366&bih=643 Check those links too: http://tapestryjava.blogspot.com/2008/09/tapestry-5-ioc-introducing-service.html http://jumpstart.doublenegative.com.au/jumpstart/examples/input/translators1 http://jumpstart.doublenegative.com.au/jumpstart/examples/input/creatingtranslators1 Then love tapestry even more :) Good luck.

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

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
