Request #11304

And this actually has to be done in Horde_Form and Horde_Core.

Unfortunately we cannot determine from the form field renderer whether 
the field allows multiple addresses. This has to be exposed in the 
future, so that we can add the "multiple" attribute if necessary.

Hi,
I updated just to horde4. And I updated to Firefox 10. In turba I was 
using its own sql datasource and did configure for the email field 
allow_multi.
When I try to save a contact with more then one email adress the 
browser doesnt save it. It generates an popup saying that the email 
address is not valid.
For IE8 it is working. Chrome and Firefox have introduced a email 
field validation. This is validating the field of the type=email for a 
single email address.
In Chrome it was possible to switch of the HTML5 Form validation using 
a flag (found under chrome://flags).
I didnt find any flag or parameter for FF10. There it only worked 
following change of the HTML code:
I changed:
<input id="object_emails_" type="email" value="test@test.de, 
test@test.com" name="object[emails]">
to
<input id="object_emails_" type="email" multiple value="test@test.de, 
test@test.com" name="object[emails]">
This variable was document on the mozilla developer page.

I didnt find the place in the horde code to add such a parameter, and 
so far I dodnt know how IE and Chrome will react on it.

I hope this is enough informaiton. Many thanks for you help
