    DelegatedController, ComponentAware, org.springframework.beans.factory.Aware, org.springframework.context.ApplicationContextAware, org.springframework.web.context.ServletContextAware, org.springframework.web.servlet.mvc.Controller
    public class ElementComponentController
extends ComponentController
    This class is the delegation controller for elements. Note that this controller is not running in the Spring application context. It is only used for controller delegation from a MainSpringController which runs inside the Spring application context. Custom controllers for element components should extend this class.

      • onSubmit

        public void onSubmit​(javax.servlet.http.HttpServletRequest request,

              throws Exception
