How to submit a form with checkboxes in a page flow?

Question

I'm having some trouble with a form that contains several checkboxes, and
how to submit this form within a page flow...
I have a JSP page containing a form with N checkboxes. The value and
checked/unchecked status of each checkbox is generated from parsing an XML
document. Here is the (simplified) code:
<%@ taglib uri="http://java.sun.com/jstl/xml" prefix="x" %>
<netui:form action="doUpdate">
<x:forEach select="...">
<input type="checkbox" name="id"
<x:if ...>checked</x:if> value="<x:out ... />">
</x:forEach>
<netui:anchor formSubmit="true" action="doUpdate">Submit</netui:anchor>
<netui:anchor action="doCancel">Cancel</netui:anchor>
</netui:form>
When this form is submitted, the checkbox values are lost -- the following
code (in the action) produces an empty array:
String[] prefs = this.getRequest().getParameterValues("id");
I looked at the <netui:checkbox> tag, but it does not appear to give me a
way to set the state and value (unless I've missed something).
Can I submit a form without using a form bean? If I do use a form bean, can
I set the state and value from my JSP?
Any suggestions on how to do this (or insights into what I'm doing wrong)
are welcome...

I am new to this, but I think this may solve your problem:
I am not sure if this is what you are looking for, but you can create a LinkedHashMap
with the req key/value pairs in the page-calling action in the pageflow and then
pass that via a getRequest().setAttribute("myCheckboxes",myCheckboxHashMap);
You can then access it in code using the optionsDataSource portion of the netui:checkBoxGroup
- ie
<netui:checkBoxGroup dataSource="{actionForm.thisCheckbox}" optionsDataSource="{request.myCheckboxes}">
Hope this helps!
