I want to call a not-default controller and a not default Action in a my plugin.
Try
I use the viewhelper f:form in my fluid-template with the needed parameters.

           <f:form method="post" 
                    controller="Bubble" 
                    action="{actionType}{actionFields}{actionParent}" 
                    pageType="{f:if(condition:'{loadtype}=={settings.frontendEditing.ajaxLoadType}',then:'{settings.frontendEditing.ajaxTypeNum}',else:'{settings.frontendEditing.redirectTypeNum}')}" 
                    arguments="{parent:parent}" 
                    additionalParams="{switcher:plugIn}" 
                    pluginName="{plugIn}" 
                    name="bubble" 
                    object="{bubble}" 
                    id="{ridForm}" 
                    class="[ js-form-fe ]" 
                    additionalAttributes="{ data-error:         '{f:translate(key:\'LLL:EXT:positioner/Resources/Private/Language/locallang_backend.xlf:tx_positioner_domain_model_bubble.update.error\')} {infoText.error}',
                                            data-success:       '{f:translate(key:\'LLL:EXT:positioner/Resources/Private/Language/locallang_backend.xlf:tx_positioner_domain_model_bubble.update.success\')} {infoText.success}',
                                            data-action-reload: '{f:translate(key:\'LLL:EXT:positioner/Resources/Private/Language/locallang_backend.xlf:tx_positioner_domain_model_bubble.question.{actionType}\')}',
                                            data-actiontype:    '{actionType}',
                                            data-type:          menuDataReaction
                                        }"

The Veiwhelper redirect me to the default-Action of my controller.

Reason
The viewhelper don't respect its parameter. It build the wrong parameter in the hidden @request-Part of the form.
The wrong result were for example:

<input name="tx_positioner_cartoon[__referrer][@extension]" value="Positioner" type="hidden">
<input name="tx_positioner_cartoon[__referrer][@vendor]" value="Porth" type="hidden">
<input name="tx_positioner_cartoon[__referrer][@controller]" value="Cartoon" type="hidden">
<input name="tx_positioner_cartoon[__referrer][@action]" value="detail" type="hidden">
<input name="tx_positioner_cartoon[__referrer][arguments]" value="YTowOnt9fb66287f032eff31613853e997bfe87205fd0194" type="hidden">
<input name="tx_positioner_cartoon[__referrer][@request]" value="a:4:{s:10:"@extension";s:10:"Positioner";s:11:"@controller";s:7:"Cartoon";s:7:"@action";s:6:"detail";s:7:"@vendor";s:5:"Porth";}d29f832dadf2269189da2e1c49cbe84d37547681" type="hidden">
<input name="tx_positioner_cartoon[__trustedProperties]" value="a:2:{s:6:"bubble";a:3:{s:4:"name";i:1;s:7:"opacity";i:1;s:12:"themeclasses";i:1;}s:10:"cancelForm";i:1;}11c64f4a232105b5272d97afe197564ae9f9b9e6" type="hidden">

Solution
I defined myown form-viewhelper, which replaced one mistaken protected method in the following way

class FormViewHelper extends \TYPO3\CMS\Fluid\ViewHelpers\FormViewHelper
{

    /**
     * Renders hidden form fields for referrer information about
     * the current controller and action.
     *
     * @return string Hidden fields with referrer information
     */
    protected function renderHiddenReferrerFields()
    {
        $request = $this->renderingContext->getControllerContext()->getRequest();
        $extensionName = (empty($this->arguments['extensionName']) || is_null($this->arguments['extensionName'])) ?
            $request->getControllerExtensionName():
            $this->arguments['extensionName'];
        $vendorName = (empty($this->arguments['vendorName']) || is_null($this->arguments['vendorName'])) ?
            $request->getControllerVendorName():
            $this->arguments['vendorName'];
        $controllerName = (empty($this->arguments['controller']) || is_null($this->arguments['controller'])) ?
            $request->getControllerName():
            $this->arguments['controller'];
        $actionName = (empty($this->arguments['action']) || is_null($this->arguments['action'])) ?
            $request->getControllerActionName():
            $this->arguments['action'];
        $actionRequest = [
            '@extension' => $extensionName,
            '@controller' => $controllerName,
            '@action' => $actionName,
        ];
        $arguments= ((count($this->arguments['arguments']) <= 0)? $request->getArguments() : $this->arguments['arguments']);

        $result = LF;
        $result .= '<input type="hidden" name="' . $this->prefixFieldName('__referrer[@extension]') . '" value="' . $extensionName . '" />' . LF;
        if ($vendorName !== null) {
            $result .= '<input type="hidden" name="' . $this->prefixFieldName('__referrer[@vendor]') . '" value="' . $vendorName . '" />' . LF;
            $actionRequest['@vendor'] = $vendorName;
        }
        $result .= '<input type="hidden" name="' . $this->prefixFieldName('__referrer[@controller]') . '" value="' . $controllerName . '" />' . LF;
        $result .= '<input type="hidden" name="' . $this->prefixFieldName('__referrer[@action]') . '" value="' . $actionName . '" />' . LF;
        $result .= '<input type="hidden" name="' . $this->prefixFieldName('__referrer[arguments]') . '" value="' . htmlspecialchars($this->hashService->appendHmac(base64_encode(serialize($arguments)))) . '" />' . LF;
        $result .= '<input type="hidden" name="' . $this->prefixFieldName('__referrer[@request]') . '" value="' . htmlspecialchars($this->hashService->appendHmac(serialize($actionRequest))) . '" />' . LF;

        return $result;
    }

}

The method now respect the entries of the form-viewhelper. The generated form has the needed hidden fields.

<input name="tx_positioner_cartoon[__referrer][@vendor]" value="Porth" type="hidden">

remark parameter actionUri
I tried to use the f:uri.action-viewhelper to define the argument of actionUri. It don't work. I think, it make the same mistake as the f:form-viewhelper; BUT I havn't analysed the way of problem in detail.

second remark
The problem with the buggy f:form-viewhelper seems to be old. I found a two year old question in stackoverflow.
