Sorry - didn't realise you were using javascript validation (should have
read your post more carefully).
You could add your own client side code:
<script>
function checkTheBox() {
if (!document.forms['yourForm'].myCheckbox.checked) {
alert("you must check the box to proceed");
return false;
} else {
return true;
}
}
</script>
<html:form action="/yourAction.do" onsubmit="return checkTheBox();">
<html:checkbox property="myCheckbox" value="true" />
</html:form>

But, when I mark it "required" in my validator.xml, it doesn't work.
The javascript that is generated (validateRequired) does not apply to
fields of type "checkbox". I suppose I could modify the javascript, but
I want both server side and client-side validation.

What makes a checkbox unusual is that it only submits a value when
checked - when unchecked nothing is submitted. You should therefore be
able to validate that it's been checked with a standard "required"
validator.

Subject: Single Checkbox Required
I have searched the archive of the list and I came up empty.
I want to use validator.xml to indicate that a single checkbox must be
checked 'true' on my form. Has anyone had success simply indicating a
boolean field to be "required"?
I've noticed that in the client-side javascript that is generated,
validateRequired does not look at fields of type 'checkbox'.
I have read that commons-validator added this functionality at some
point in the past, but has it not made it into the Struts validtion
package?
Thanks,
Michael
