More googling I did find a solution to my problem. In essential, I
RTFM. Here is the blurb from
http://tetlaw.id.au/view/javascript/really-easy-field-validation
"*To use the validate-one-required validator you must first add the
class name to only one checkbox/radio button in the group (last one is
probably best) and then place all the input elements within a parent
element, for example a div element. That way the library can find all
the checkboxes/radio buttons to check and place the validation advice
element at the bottom of the parent element to make it appear after
the group of checkboxes/radio buttons."
<div id="strategies">
<?brail
items = FormHelper.CreateCheckboxList("project.strategies",
strategies, { @value: 'Id', @text: 'Name' })
for item in items:
output items.Item()
output item.Name
?>
<br />
<?brail end ?>
<input type="hidden" class="validate-one-required" />
</div>
I placed the hidden input so that I didn't have to figure out how to
place the class on the last checkbox in my list.
