[TYPO3-english] Fluid StandaloneView and AJAX

[Alexander Dorn]

Hi Wido,

the objectManager is loaded. My description was crap. :)

The function listApartmentAction is called via an eID-Script. This works fine and the function is executed correctly. 

The debugger shows me that all variables and the instance of the StandaloneView ($ajaxView) are initialized correctly.

The last line however produces an error.
>> $ajaxView->renderSection('ajax', array('viewMode', 'listView'));

This first block from this function looks like this:
public function renderSection(...) {
	$renderingContext = $this->getCurrentRenderingContext();
	if ($this->getCurrentRenderingType() === self::RENDERING_LAYOUT) {
		// in case we render a layout right now, we will render a section inside a TEMPLATE.
		$renderingTypeOnNextLevel = self::RENDERING_TEMPLATE;
	} else {
		$variableContainer = $this->objectManager->get('TYPO3\\CMS\\Fluid\\Core\\ViewHelper\\TemplateVariableContainer', $variables);
		$renderingContext = clone $renderingContext;
		$renderingContext->injectTemplateVariableContainer($variableContainer);
		$renderingTypeOnNextLevel = $this->getCurrentRenderingType();
	}
	...
}
The error occurs when cloning the NULL-Object (underlined line)

In line 1 the following function is called and always returns NULL:
protected function getCurrentRenderingContext() {
	$currentRendering = end($this->renderingStack);
	return $currentRendering['renderingContext'];
}

The renderingStack is NULL so I have to fill this somehow. I got no clue what to do here.

If anyone knows what to to, please help me. :)

Thank You

Alexander
