Tapestry failing to inject a service into a Translator with @Inject?

[Julien Martin]

Hello,
I have the following Translator implementation:

package com.bignibou.web.services;

import com.bignibou.domain.Postcode;
import com.bignibou.service.BignibouService;
import org.apache.tapestry5.Field;
import org.apache.tapestry5.MarkupWriter;
import org.apache.tapestry5.Translator;
import org.apache.tapestry5.ValidationException;
import org.apache.tapestry5.ioc.annotations.Inject;
import org.apache.tapestry5.services.FormSupport;




public class PostcodeTranslator implements Translator<Postcode> {

    @Inject
    BignibouService service;

    @Override
    public String getName() {
        return "postcodeTranslator";
    }

    @Override
    public String toClient(Postcode value) {
        return value.getPostcode();
    }

    @Override
    public Class<Postcode> getType() {
        return Postcode.class;
    }

    @Override
    public String getMessageKey() {
        return "postcodeTranslator-parse-exception";
    }

    @Override
    public Postcode parseClient(Field field, String clientValue, String
message) throws ValidationException {
        try {
            String[] postcodesIds = clientValue.split(",");
            int postcodeId = Integer.parseInt(postcodesIds[0]);
            return service.loadPostcodeById(postcodeId);*//NULL POINTER
EXCEPTION HERE!!!*
        } catch (RuntimeException e) {
            e.printStackTrace();
            throw new ValidationException(message);
        }
    }

    @Override
    public void render(Field field, String message, MarkupWriter writer,
FormSupport formSupport) {

    }
}

Unfortunately it seems that my service is not properly injected by @Inject
and I get a NPE when I tried to use my service variable.

Note that this does not occur with a ValueEncoder implementation that I use
elsewhere in the application...

Can anyone help please?

Regards,

Julien.
