Hello Stanislav,
controller will be controls the execusion, if u run your application, controller will execute first and view will be next. so if u create instance in view and if u r going to control the execution from view itself then what is the need of the controller.As of my knowledge it is going opposite to MVC architecture(UI5 follows MVC). And of course in JSP u can do control by view itself but that type of application is not follows MVC.
Thanks,
Santhosh Gowda
