Wrong language for errormsg cl_htmlb_inputfield [type=DATE/DOVALIDATE=true]

Hello,

I am using the cl_htmlb_inputfield Element with the option dovalidate=true, but when the user enters a wrong date, the message is: "Bitte Datum in der Form DD.MM.YYYY eingeben" - this should be in english!

The system- and browser-language is English (EN).

(I don't know the patch level for the WebAS/NW, maybe there is already a patch for this problem?)

Code:

CLEAR lr_input.
CREATE OBJECT lr_input.

lr_input->invalid    = 'false'.
lr_input->alignment  = 'RIGHT'.
lr_input->size       = '10'.
lr_input->maxlength  = '10'.
lr_input->showhelp   = 'TRUE'.
lr_input->type       = 'DATE'.
lr_input->dovalidate = 'true'.
lr_input->required   = 'false'.
lr_input->visible    = 'X'.
lr_input->id         = 'DUE_DATE'.
