Hello!
I'd try using one of the methods of FieldTranslatorSource, starting
with createTranslator(ComponentResources componentResources, String
translatorName);. It's exactly the one used by the "translate" binding. The
ComponentResources should be the one of the field (i.e. you'll need
to @InjectComponent private Component price1; and pass
price1.getComponentResources() to FieldTranslatorSource.createTranslator().
