TYPO3 Core

Comming from the surfcamp, I've tried to setup my content rendering without fluid_styled_content (not installed in project). And therefore came up with the following typoscript configuration using RecordTransformationProcessor to fetch the content elements:

# Default configuration for content elements which are using FLUIDTEMPLATE directly
lib.contentElement >
lib.contentElement = FLUIDTEMPLATE
lib.contentElement {
  templateName = Default
  templateRootPaths {
    0 = EXT:site-distribution/Resources/Private/Templates/Content/
    10 = {$content.templates.templateRootPath}
  }
  partialRootPaths {
    0 = EXT:site-distribution/Resources/Private/Templates/Content/Partials/
    10 = {$content.templates.partialRootPath}
  }
  layoutRootPaths {
    0 = EXT:site-distribution/Resources/Private/Templates/Content/Layouts/
    10 = {$content.templates.layoutRootPath}
  }
  dataProcessing {
    5 = record-transformation
    5 {
      table = tt_content
      as = data
    }
  }
}

With this configuration "data" is now of type TYPO3\CMS\Core\Domain\Record instead array (compared to the fluid_styled_content way):

This results in forms not being rendered as the pi_flexform values are not recogniced in the f:cObject. (See second debug which is from "Render.html" of the Forms extension).

<f:cObject typoscriptObjectPath="tt_content.{data.CType}.20" data="{data}" table="tt_content" />

For Objects the f:cObject Viewhelper calls ObjectAccess::getGettableProperties() which doesn't resolve the pi_flexform field:

        if (is_object($data)) {
            $data = ObjectAccess::getGettableProperties($data);
        } elseif (is_string($data) || is_numeric($data)) {
            $currentValue = (string)$data;
            $data = [$data];
        }

Possible solutions:
1. Convert Record to array for f:cObject call
2. Check for type RecordInterface and use ->toArray() in f:cObject Viewhelper
3. ...
