Undeclared arguments passed to ViewHelper TYPO3\CMS\Fluid\ViewHelpers\Form\SelectViewHelper: onchange.

In latest Typo3 11.5.41 this Error is shown when entering the LDAP/SSO backend module. Undeclared arguments passed to ViewHelper TYPO3\CMS\Fluid\ViewHelpers\Form\SelectViewHelper: onchange. Valid arguments are: additionalAttributes, data, aria, name, value, property, class, dir, id, lang, style, title, accesskey, tabindex, onclick, size, disabled, options, optionsAfterContent, optionValueField, optionLabelField, sortByOptionLabel, selectAllByDefault, errorClass, prependOptionLabel, prependOptionValue, multiple, required

I still receive the same error. Looks like the SelectViewhelper is still evaluated although the section is not used.

I tested the extension under Typo3 12 and there I also get the same error. In the Typo3 documentation I can't find onchange as a property on the SelectViewHelper.

Ah, interesting, thanks for the follow-up, I must admit my latest test was with ~TYPO3 v13~ TYPO3 v12, strange [edit].

Just debugged in TYPO3 v12, onchange is indeed an undeclared argument, but it is "catched" in

• vendor/typo3fluid/fluid/src/Core/ViewHelper/ViewHelperInvoker.php:78 then passed to
• vendor/typo3fluid/fluid/src/Core/ViewHelper/AbstractTagBasedViewHelper.php:171 as argument to be added just like that.

However, I just think that we could certainly do that instead (only for TYPO3 v12 and up):

Yes, that works under Typo3 v11 as well and removes the need to have separate handling between v11 and v12+.
