Issue with Custom Tile

I am developing a simple SplitApp application in sapui5. I have a HomeView and a SplitApp in App. I have a custom header in my HomeView with a button on right to navigate to the SplitApp. When I try to add a customTile in SplitApp's MasterView, it gives me an error - " uncaught TypeError: Cannot call method 'render' of undefined ". It works fine with Tile.
