Struts2 s:checkbox - unwanted input type hidden
Question
My code:
<label class="btn btn-default">
<s:checkbox name="viewTypeDescr" /> 
<s:text name="name.contentType" />
</label>
The docs: http://struts.apache.org/release/2.3.x/docs/checkbox.html say that it will render a input[type=checkbox]
Instead here's what I get:
<label class="btn btn-default">
<input type="checkbox" name="viewTypeDescr" value="true" id="search_viewTypeDescr">
<input type="hidden" id="__checkbox_search_viewTypeDescr" name="__checkbox_viewTypeDescr" value="true">
Content Type
</label>
That added input[type="hidden"] is making the resulting page invalid because a label can have max 1 input inside.
Definition of invalid:
- Go to validator.w3.org
- Paste the provided HTML code in "Validate by direct input"
- Decor it with missing
<html><head><title>foo</title></head><body>and</body></html>to lessen the false errors - Select HTML5 ad doctype
- Click "Validate"
- Get this error: "Line xyz, Column abc: The label element may contain at most one input, button, select, textarea, or keygen descendant."
- Go to spec just in case: "The caption can be associated with a specific form control, known as the label element's labeled control, either using the for attribute, or by putting the form control inside the label element itself."
- Discover that "If the for attribute is not specified, but the label element has a labelable element descendant, then the first such descendant in tree order is the label element's labeled control."
- Add that hidden can't be there " http://www.w3.org/html/wg/drafts/html/master/forms.html#category-label "
Anyway, when you submit your document to QA for validation, they use validator.w3.org and that is all that matters.
What's the reason of that hidden? How could I get rid of it or move it elsewhere?

I created a new theme, with parent=simple, and will use that.
Still don't know what's the supposed purpose of that hidden...
