Return Code Parameters are not Handled Persistently in JOE

Current Situation
Return code parameters can be easily deleted by mistake due to non-standard behavior of form buttons.

• Set a Return Codes for a job and then save the configuration
• Reopen the 'Return Codes' form for the job with the 'Return Code' button.
• Close this form using either with the form 'Cancel' button or the 'X' in the top right corner.
• Reopen the form
• The return code values are now no longer shown.
• If the configuration is now saved again the code values will be permanently deleted from the configuration.
  This is not normal behavior for 'Cancel' or 'X' buttons.

Workaround
Return code values are preserved if the 'Return Codes' form is closed using the form's 'Apply' button.

Desired Behavior
Use of the 'Cancel' or 'X' buttons 'Return Codes' form should conserve current values - i.e. the Editor in-memory returned to the state before the Form was opened.
