A view with App tag

[Former Member]

Hi all,

Suppose we have two pages, page 1 and page 2, which are corresponding to view 1 and view 2.

Now I have a requirement of navigation from page 1 to page 2, for example, by clicking a button on page 1.

I am wondering if I need App tag in both page 1 and page 2.

Actually, I have gone through the demo and take it as reference, but I didn't get it worked.

I noticed that the demo uses nested views. Only in the root view, App tag is used. Does that matter?

Hi Ming,

Navigation in UI5 can be done via Event bus of App or using a Router Mechanism.

If you created application, by keeping sap.m.App at the top level, you can use event bus mechanism directly.

Assume, oApp = new sap.m.App();

               oApp.addPage(page1);

               oApp.addPAge(page2);

then on click from page1, you can navigate to page 2, just by oApp.to(page2, context);

For broader explanations, please search SCN for Navigation. There are lot of threads and blogs available

Thanks, so do you mean that there is only one App in a project and it can be only put in the root view?

Hi Ming,

Yes Ideally there should be only one App, which will be the root UI for all pages.

However you can achieve a plain app or a master-detail app within this architecture.

Thank you, one more question if you allow me, which one you prefer, event bus or router?

Hi Ming,

Routing is preferred. For more info please look at the below references.
