Bug #52147 for HTML-FormFu: HTML::FormFu::Element::reCAPTCHA with Catalyst::View::ContentNegotiation::XHTML

Hi there, I'm trying to get working HTML::FormFu::Element::reCAPTCHA on a XHTML 1.1 Strict (tested also with 1.0 Transitional) site rendered using the Catalyst::View::ContentNegotiation::XHTML. There is a bug somewhere because when I switch from "normal" View:TT (see working.png) to the XHTML View (see not-working.png), the reCAPTCHA element doesn't show up though I haven't changed anything else. The problem is on the reCAPTCHA's side becuase it seems that the XHTML doctype is not supported (http://rickardandersson.com/recaptcha-and-xhtml and many more pages on Google). This is the element source YML: - type: reCAPTCHA name: recaptcha public_key: [pubkey] private_key: [privkey] recaptcha_options: custom_translations: instructions_visual: Opište výše uvedená slova instructions_audio: Napište, co jste slyšeli visual_challenge: Zobrazit textovou verzi audio_challenge: Poslechnout si zvukovou verzi (anglicky) refresh_btn: Nemohu slova přečíst, vygenerovat nová help_btn: Nápověda (anglicky) cant_hear_this: Stáhnout nahrávku jako MP3 incorrect_try_again: Chyba. Zkuste to znovu play_again: Přehrát nahrávku znovu ==> Older (without XHTML) view: package Entropy::View::HTML; use strict; use utf8; use base 'Catalyst::View::TT'; __PACKAGE__->config({ ... ==> Newer (with XHTML) view: package Entropy::View::HTML; use strict; use utf8; use Moose; use namespace::clean -except => 'meta'; extends 'Catalyst::View::TT'; with 'Catalyst::View::ContentNegotiation::XHTML'; __PACKAGE__->config({ ... ==> Generated form source: <div class="recaptcha constraint_recaptcha"> <span class="elements"> <script type="text/javascript"> //<![CDATA[ var RecaptchaOptions = {"custom_translations":{"audio_challenge":"Poslechnout si zvukovou verzi (anglicky)","cant_hear_this":"Stáhnout nahrávku jako MP3","help_btn":"Nápověda (anglicky)","incorrect_try_again":"Chyba.

"Operation is not supported" code: "9" nsresult: "0x80530009 (NS_ERROR_DOM_NOT_SUPPORTED_ERR)" location: "https://api-secure.recaptcha.net/challenge?k=6LcUTQgAAAAAAFKx0HJ1hBDR7ir2vfx3IEc%2dH3tp Line: 12"] This points to the reCAPTCHA service. Is there any possibility of fixing this with some workaround? Should I stuck at plain HTML until it's fixed in the reCAPTCHA API instead?
