[FLOW3-general] Ajaxable Actions / JSON as content-type

[David Schoen]

Hello List,

can anyone tell me how to make an action ajaxable? I would like to call 
an action with an JSON-request and would like to get the answer in JSON 
so I would have to change the content-type.

Here is what I imagine:

/**
* Returns some json-object
* @someAnnotationToSetTheReturnTypeToJSON
* @return void
*/
public function jsonAction() {
	...
	return <someJsonObject>;
}

I can't find anything about that in the documentation or the 
blog-example. If you have any clue, tip or link, please answer :)

Thanks in advance,
David
