I'm developing SAP Fiori app with master detail template. i'm having troubles,I need to update a particular data every 5 seconds, but i don't want to refresh the entire model because it takes too long to render.
Any idea how to do that?
You could try to refresh the Binding on your control. For example:
sap.ui.getCore().byId("myList").getBinding("items").refresh();
Depending on the type of Model you are using this would send a more focused request.
