Great, thanks, that solves my problem. My confusion was that I had not realized that I would get the same exception even without contributing or referencing any translator, because I was binding my TextField to a Date and not to a String so a translator was needed in any case.
My goal is that only TextFields having the t:translate="dateTranslator" attribute in the tml get translated, and TextFields that don’t have such attribute should keep behaving as they did before (in this case throw an exception if I bind that field to a Date). So I will keep contributing my translator by name to TranslatorAlternativesSource and use t:translate in the tml; then if I want a TextField to show a “non-translated” date I will not give that field the t:translate attribute and I will bind that field to a String instead of a Date, and I will provide a String representation of my Date as the field’s value instead of providing the Date itself. -----Original Message----- From: Thiago H de Paula Figueiredo [mailto:thiag...@gmail.com] Sent: Thursday, April 30, 2015 22:52 To: Tapestry users Subject: Re: Exception "Parameter 'translate' of component is bound to null" on a field that has no 'translate' attribute.

Exactly. TextField needs a translator to convert between the edited property type and String and vice-versa. Tapestry provides translators for numeric types and String itself. In your case, you're editing a Date, so you need to provide a translator for Date through TranslatorSource or the translate parameter explicitly. -- Thiago H. de Paula Figueiredo Tapestry, Java and Hibernate consultant and developer http://machina.com.br --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org<mailto:users-unsubscr...@tapestry.apache.org> For additional commands, e-mail: users-h...@tapestry.apache.org<mailto:users-h...@tapestry.apache.org>
