Common Controller for Parent and Nested Views

Hi, We are developing an app where we are using nested views inside main view. The main view structure is like this:

http://www.w3.org/1999/xhtml" xmlns:mvc="sap.ui.core.mvc">

I have two queries:

1. Is it good to use a common controller for all the views (nested and main)?

2, I want to access elements in nested views by id when I click on Buttons(Update/Reset) using this.getView().byId(). The problem is Buttons(Update/Reset) are in main view. So If I use different controller for main view and nested views, accessing elements of nested views in main view controller is not possible. So as as solution, I am trying to use common controller for all views. Will this approach work? If I use common controller, can I access nested view elements using method this.getView().byId() in common controller.

    In the main view controller use the following code:

    var subView = this.getOwnerComponent().byId("yourSubViewID");

    Then you can access elements from the subviews by using:

    var button = subView.byId("btnId");

    Hello Vinayak,

    You still can access the main view from nested controller (I hope you would be using Routing for Navigation between the views). Try something like below:

    var oRouter = sap.ui.core.UIComponent.getRouterFor(this);
    var oMainView = oRouter.getView("mainviewpath");  //Mention your main view path instead of 'mainviewpath'
    var oButton = oMainView.byId("oButton");

    Thank you!

    Best Regards,

    Sai.
