thats what i wrote and thats my problem. i dont want to remove the parent element to destroy a controller. because thats what i need to append another controller.You can remove the element from the DOM, which will also destroy the Control instance. Or, if you want to keep the element in the DOM, you can call destroy on the Control instance to remove the bindings.
i want to load different controllers in the same element. it´s a regular use case in a one-page app i thinkSo what exactly are you trying to do. What do you mean you want to "exchange" widgets?
