    • dp_empty_change (settable, context: empty, enable, scirpt: "return 11;", Update event: Context change) ,
    • dp_empty_update (settable, context: empty, enable, script: "return 10;" Update event: Context update);
  3. Go to Watch Lists;
  4. Create Watch List as wl_1 with points:
    • meta_1 - dp_empty_change,
    • meta_1 - dp_empty_update;
  5. Set values:
    • meta_1 - dp_empty_change to 123;
    • meta_1 - dp_empty_update to 321;
  6. Restart tomcat;
  7. Login as admin;
  8. Go to Watch Lists and select wl_1 then values;
    • meta_1 - dp_empty_change is 11 -> error 1,
    • meta_1 - dp_empty_update is 10 -> error 2; The script was recalculated on initialization despite an empty context.
