Spring MVC Form Checkbox vs Checkboxes

[Mick Common]

Hi all,
I am facing strange problem with form:checkbox attribute in my Spring MVC form. I am trying to display and edit checkbox values and I don't understand why "form:checkboxes" is working and "form:checkbox" is not.

Here is my code:

                    form:checkboxes
                    <form:checkboxes path="packing" items="${packList}" itemValue="id" itemLabel="name" />
                    <br /><br />
                    form:checkbox
                    <c:forEach items="${packList}" var="pack" varStatus="packStatus">
                        <form:checkbox path="packing"  value="${pack.id}" label="${pack.name}" />
                    </c:forEach>

The result page screenshot is attached. First checkbox is working, the second one in forEach is not checked and I do not why.


Am I doing anything wrong?
Unfortunately I have to use checkbox with forEach to add more elements.

I am using Spring version 5.1.9.RELEASE

Any advice is appreciated!

I am not familiar with Spring MVC form.
But one experiment you can first try is to replace the forEach by multiple checkbox, like this example:

Thanks for the replay, I already tried "checkboxes" element and it is written in my post, this approach works! Unfortunately I need to use checkbox inside forEach to add more elements.
