Make errors also display in proper format and language I used webform and Internationalization. It works fine, but when error message are displayed, it shows in partial english and RTL and LTR is mixed up as shown in image.

how do i correct it.
Either import translation for Webform, or keep in synch with i10n.

If the string ('field is required') is not translated, you have to do it yourself in the translation interface admin/config/regional/translate.
