[TYPO3-english] Form Framework - Frontend rendering generates a bad action

Fri Oct 20 11:48:27 CEST 2017

Hi guys. I have a problem with form framework in typo3 v. 8.7.8

The Url address in the form which is embedded in the site content is OK
/?ajax=1&tx_form_formframework%5Baction%5D=perform&tx_form_formframework%5Bcontroller%5D=FormFrontend&cHash=503549aca041d1cbf99b7c288282e943#newsleterForm

The Url address in the form which is embedded using fluid template generates wrong url address
/?ajax=1&tx__%5Baction%5D=perform&tx__%5Bcontroller%5D=Standard&cHash=ee96f42474e7bc2f9f4d87d89e35ac39#newsleterForm

html code:

<html xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers" xmlns:formvh="http://typo3.org/ns/TYPO3/CMS/Form/ViewHelpers" data-namespace-typo3-fluid="true">
<!-- Modal -->
<div id="newsletterModal" class="modal fade" role="dialog">
    <div class="modal-dialog">

        <!-- Modal content-->
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal">×</button>
                <h4 class="modal-title"><f:translate key="LLL:fileadmin/Language/locallang.xlf:domain_model_breadcrumb.subscribe_to_newsletters"></f:translate></h4>
            </div>
            <div class="modal-body">

                <formvh:render persistenceIdentifier="1:/introduction/form/newsletter.yaml" />

            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal"><f:translate key="LLL:fileadmin/Language/locallang.xlf:domain_model_breadcrumb.close"></f:translate></button>
            </div>
        </div>

    </div>
</div>
</html>

yaml config code:

        last_name:

        email:
          value: '{data_email}'

    renderingOptions:

    identifier: page-1
    renderables:
      -
        defaultValue: Meno
        type: Text
        identifier: data_firstname
        label: Meno
      -
        defaultValue: 'Priezvisko'
        type: Text
        identifier: data_lastname
        label: Priezvisko

        defaultValue: 'peto.rosinsky (at) gmail.com'
        type: Text
        identifier: data_email
        label: Email

How can I set up JSON response when sending out the form via jQuery ajaxForm?
