Hallo Stefan,
mit dem neuen Property-Mapper habe ich es bis jetzt nicht zum Laufen
gekriegt. Ich habe gerade vor wenigen Minuten auf der MVC-Liste
geposted. Ich zitiere hier einfach mal
(wahrscheinlich verstösst das gegen 100 Mailinglists-Regeln, hihi):

Hi Jonas,
I couldn't find a neat solution yet...
I'm doing it now without "property" argument, but by naming the form
fields by myself, like:
<f:form.checkbox name="categoryArray[{category.uid}]" value="true"
checked="{h:hasCategory(shop:shop, category:category)} />
As you can see I still need an array and also a custom viewhelper for
setting the flags properly.
BR,
Till
