3761229 - Retain Treetable expansion state after refresh without rowsupdated in version 1.71.71

Symptom

  • An application uses a TreeTable bound to a two-level OData model.
  • After starting a data refresh, expanded nodes collapse back to the default root state.
  • The requirement is to retain the exact pre-refresh expansion state for first- and second-level nodes.
  • The current version in use (1.71.71) does not support the rowsUpdated event.
