FormTag generates hidden fields from RequestDataValueProcessor.getExtraHiddenFields(...) without container, resulting in invalid xhtml [SPR-10926]

[spring-projects-issues]

Thorsten Vogel opened SPR-10926 and commented

When specifying extra hidden fields in a RequestDataValueProcessor, the resulting markup is invalid according to the W3C validator. We are using XHTML 1.0 Strict.

It would be great if the FormTag.writeHiddenFields(...) method could optionally generate a container around the fields (e.g. div or a configurable container).

Resulting markup:

...
    <input type="hidden" name="_token" value="xyz" />
</form>

Expected for compliancy:

...
    <div>
        <input type="hidden" name="_token" value="xyz" />
    </div>
</form>
