APAR status

• Closed as program error.

Error description

• It seems that you can crash the editor while trying to add a
  variable update descriptor to a screen.  It only happens when
  you select a variable that is not the first one in the list.
  
  Steps to recreate:
  1. Create a new macro by hitting record, then stop.
     *** You do not need to actually record anything in the macro,
  we want it empty. ***
  
  2. Check the box for "Use Variables and Arithmetic Expressions
  In Macro"
  
  3. Go to the Variables tab and create 2 integer variables called
  $count$ and $index$.
  
  4. Now switch to the Screens tab and then select the Description
  tab for Screen 1.
  
  5. From the dropdown list, select <new variable update>.
  
  6. Select the second item ($index$) in the Name dropdown at the
  bottom.
  
  Now the editor is broken and can no longer be used with this
  macro.
  Click Save and Exit to close the macro.
  Now try to open the editor again to edit this macro.
  HOD will gray out the Macro Manager bar and nothing else can be
  done with macros in this session until it is closed and
  reopened.
  
  You can check the Java console and see the following exception
  is thrown:
  
  Exception in thread "AWT-EventQueue-4"
  java.lang.StackOverflowError

  ****************************************************************
  A StackOverFlowError is thrown when creating a variable
  update descriptor in a HOD macro.  This is due to a scenario
  where recursive calls are generated when the Descriptor Value
  panel tries to notify the Descriptor ID panel to change its
  content according to the choice made.
  

Problem conclusion

• The problem was solved by adding a condition to avoid this
  recursive call scenario.
  
  Fix is scheduled for HOD 10.0.8 Refresh Pack
  Fix is scheduled for HOD 11.0.2 Refresh Pack
  

Temporary fix
