Can't you just use the 'required' validation rule? Or possibly a
validwhen with something like *this* != null and *tihs*.length >= 1?
Admittedly I haven't tried either, though.

I've always wanted this feature myself. However, no such validation
exists.. but if you write it, you could share it back to the Struts
community.
So you'll have to add this validation yourself by override the
validate() method of your form, checking the property's length; if it is
not null then add your message to the existing error messages.

Can struts validator validate that at least one checkbox in a set is
checked? I guess somehow it has to validate that a String[] array
property
of the form has size of 1 or more, but I dont know how.
