Prior to SPS11/12 custom applications (with Component.js) could be specified as navigation targets in sap.hana.uis.db::NAVIGATION_TARGET
See Navigation Target and Target Mapping - SAP HANA Developer Guide for SAP HANA Studio - SAP Library
For example
VIEW_NAME:
SAPUI5.Component=test.testapp (where the 'testapp' package contains the Component.js file)
In general UIS calatog (xswidget) and UIS Application Site (xsappsite) don't yet seem to be supported by the new WebIDE
See Creating a Launchpad Site - SAP HANA Developer Guide for SAP HANA Studio - SAP Library
Fortunately using Hana studio a custom Fiori Launch Pad can still be created using the old method.
Is it possible to point the VIEW_NAME to a new XSA based app? If so does anyone know the syntax to use?
E.g.
VIEW_NAME:
SAPUI5.Component=<??XSA App??>.tinyworld (assuming the XSA app 'tinyworld' has a Component.js file)
Or perhaps the Native Hana Fiori Launch Pad is currently restricted to using the old XS apps.
