[TYPO3-dev] Extbase: Create multiple objects within one formular

[Frank]

Hi,
I am curious, cant extbase spawn new child objects if i simply do <f:form.texfield property="{childobject.childproperty}" /> when the form itself is bound to the parentObject? This would be a basic feature you need to implementing CRUD operations via frontend form for related objects and DDD. Is that possible by now wirhout implementing own controllerAction-solutions and stuff?
