It works! :) And not only "tëxt", other types works too. :)
Is this a bug? Do i need to do that every time when i make changes in template?

Forgot to tell - Joomla 2.5.11, Artio Booking 2.0.7, PHP 5.3.17

Hello. After i changed names of Item Properties in template Cars, i received following error:

Fatal error: Cannot instantiate abstract class JFormField in /home/bgopakov/public_html/test/libraries/joomla/form/helper.php on line 119

Error exist in frontend and in backend both. Help?
