Clarification Regarding Powermail Conditions and Validation Behavior

[SimonWentland]

I have encountered an issue when using powermail_cond in combination with Powermail.

When using Powermail without conditions, the form correctly highlights invalid fields through client-side JavaScript validation, which is the preferred behavior.

However, when using Powermail with conditions (powermail_cond), the form instead displays a server-side error within the form, effectively bypassing the client-side JavaScript validation.

Could you please confirm whether this behavior is intended or if it might be the result of a misconfiguration on my side?

In previous versions, Powermail Conditions worked together with the client-side validation, and I would like to restore that behavior if possible.

Thank you in advance for your assistance.

Kind regards,
Simon

Well, I have noticed, that powermail_cond (13.1.1) kills the client-side validation of powermail.
When I submit a powermail form, the validation takes place, BUT the form will be submitted even there are errors.
I guess
n(d, t).submit()
in
PowermailCondition.js
should check if there are normal validation errors BEFORE submitting an form.
In some cases I get than an page with the PHP error:
Could not ultimately dispatch the request after 101 iterations. Most probably, a @TYPO3\CMS\Extbase\Annotation\IgnoreValidation annotation is missing on re-displaying a form with validation errors.

Without PowermailCondition.js, the clint-side validation works fine.

On TYPO3 v13.4.20 with powermail_cond 13.1.1, the issue in Safari still persists: when ALL fields are left EMPTY, the JavaScript validation is bypassed. The behavior works correctly in Chrome and Opera.

In my case the forms are submitted twice, when there's no condition for this specific form.
The forms with conditions are submitted only once.
