TYPO3 pass controller context to ajax request

I am working on a TYPO3-backend-module. The main "overview"-Action allows to upload a file via ajax upload, which gets processed in one of my controllers.

The corresponding controller-action instantiates a StandaloneView, renders it and writes the rendered content to the response body. My problem is, that I have no controllerContext set in the generated content, therefore a form, which should trigger a different extbase action, in that rendered content does not work, because the modulename is not set.

Can anybody tell me how I could possibly get/pass the controllerContext, to make it available in the controller action, which is called via ajax ? Best regards and thanks in advance, Oliver !

The main problem here is that BE modules don't exactly use a standard View implementation - in the default implementation, they wrap around a StandaloneView which by definition has no controller context.

That being said, if you can change the way the View wraps around the StandaloneView, the controller context can be copied by doing:

$view->getRenderingContext()->setControllerContext($parentView->getRenderingContext()->getControllerContext());

Alternatively you may want to copy the entire rendering context rather than just the controller context.

Advise applies to TYPO3v8 only. On 7.6 you will need to copy the Request instead.

For usages outside of MVC context you will need to manually pass the original controller context values such as controller name and module name. That means the values must be part of the link you create and must be read by the receiving code (in whichever way that code's context requires) and then manually assigned to a Request you create and pass to the sub-view. Note that this is only necessary if those MVC context values actually change - if you always call the same action next, you can get the right result by simply hardcoding the desired extension name, module name, controller name and action in the form/link in the template you render from that AJAX controller.
