[TYPO3-mvc] Using Repositories "standalone"

is this extension itself also based on extbase? Because in your code 
example you called the dispatcher directly, which is only needed if not 
in extbase context.

Why don't you do something like this, if you're already inside extbase:

/**
  * Is rendering a list of various objects, filtered by the demand object
  * @param $demand Tx_ExtKey_Domain_Model_Deman The filter demand that 
is holding the configuration of your filter
  * @param $page integer The page offset to display

function listAction(Tx_ExtKey_Domain_Model_Demand $demand, $page = 1) {
	$listItems = array();

	foreach ($demand->getObjectTypes() as $objectType) {
		$repositoryClassName = 
'Tx_YourExt_Domain_Repository_'.ucfirst($objectType->getName()).'Repository';
		$repository = $this->objectManager->get($repositoryClassName);
		$items = $repository->findDemanded($demand);

		$listItems = array_merge($listItems, $items);
	}

	// apply pagination-limit if needed, or if only one object type
	// can be rendered at a time, add pagination stuff probably in
	// your findDemanded method of the repository

	$this->view->assign('listItems', $listItems);
}
