On sceen "customer Info" I have a button to create a new activity.  The button stores the customer full name into a shared action, then executes show pop-up screen "New Activity".  In the onscreenload of new activity screen, it verifies the data and enters the full name it into the customer name field. the first time I do this for a customer everything works fine.  
However, when a save and close the new activity screen and return to customer info, then select the new activity button (to create another activity for the same customer); the new activity screen appears without the customer name.
I have verified that the data is store via the show message in the customer info screen. But, it seems as if the onscreenload does not execute.  This is becuase I have a show message (before any start conditions) in the onscreenload and it does not appear.  Furthermore, this happens to all buttons/screens: work orders, estimates, activities, etc...
