Re: AJAX & IllegalStateException: Components can no longer be added
Hi Sven, Hi, actually it is even more strict: Once the ART has started generating the response - including preparation of components - you can now longer add other components. This hasn't changed from 7.x to 8.x We were discussing on lifting this restriction, but this would come with some difficulties: what if a component in beforeRender() adds one of its ancestors to be updated? Thanks for the clarification!
