The Relation Reference widget has buttons to open a 2nd form so that records in the referenced (parent) layer can be edited or new records added.
However, when the edits are made to the parent layer and 'OK' is clicked on the 2nd form - the edits are not reflected in the list of values in the widget, unless both these are performed:
- the parent table is saved
- the form containing the Relation Reference widget is closed and reopened
How else can the Relation Reference widget be refreshed ?
