SYMPTOM(s):
Accessing a Selection-List widget on the AppServer fails
Trying to access the SCREEN-VALUE attribute
Trying to invoke the LOOKUP() method
Trying to invoke the ENTRY() method
CAUSE:
The AppServer runs as a batch Progress session and as such has no access to any kind of "screen" to display widgets. Accessing any attributes for user interface widgets that are in any frame will fail because the widgets need to be realized and there is no "screen" available to realize the widgets into.
FIX:
Modify the application code so that it does not attempt to access user interface widgets within frames on the AppServer.
