since i've start using this feature this stopped working:
screen one has a Mobile list. the mobile list has event, when ever clicking on one list item another screen will open.
before using the 'Render" feature each list item presented relevant data in the linked screen. after using this 'Render" feature the first list item getting clicked, its data will be used in the next screen for all list items.
this was confirmed by simply un-checking the render feature and testing the app again.
