The Framework fails to recognise a screen, this may happen always or occasionally.

The Trace for the screen looks like this:

     VF_CH006 Screen named has arrived and is being processed 
     VF_CH006 Screen named in a form not defined to the framework. 
     VF_CH006 Signal LockFramework is being queued. 
     VF_CH006 Signal LockFramework has been queued. 
     VF_CH006 Screen named is not a destination do function keys will be left unchanged. 

Solution

Check that:

• The form object is named in newlook design mode.
• The screen ID area covers only static elements in newlook Identify mode. In other words, the ID area must not cover field data, browselist data, system date/time, IBM i machine name, User profile or other data that can change.
