BeanValidation: HTML Markup in Tooltip of ValidationErrors

Hi.

I’m using the BeanValidation add-on and it’s great.

There is just a small thing to note:
When there is more than one validation error on a single field (e.g. NotNull and Size) both errors are displayed in the tooltip, but there is a
between them instead of the required line break.

I think the following code of the BeanValidator creates this markup:

b.append("<br/>");

But on the online demo of the add-on there is only one message per line, the linebreak seems to be interpreted.
The only difference I can see via Firebug: In my application there is a

<br/>

between the different messages and in the online demo it is

<br>

(without closing slash)

Can anyone help me, how to get to this solution?

Thanks a lot,
Horst
