[TYPO3-mvc] Error with array argument in Ajax action.

[Dirk Wenzel]

It seems I found the solution:
/**
  * Initialize ajax list action
  */
  public function initializeAjaxListAction() {
    if($this->arguments->hasArgument('overwriteDemand')) {
      $this->arguments->getArgument('overwriteDemand')
      ->getPropertyMappingConfiguration()
      ->setTypeConverter(
        $this->objectManager->get(
          'TYPO3\\CMS\\Extbase\\Property\\TypeConverter\\ArrayConverter')
        );
    }
  }

Cheers
Dirk
