I'm trying to get the involved model when a Complete event fires and a EditorEvent is passed in a grid from a CellEditor.

Code:
        TaxCombo taxCombo = new TaxCombo() {
            @Override
            public String getFormat(Tax tax) {
                return tax.getName();
            }
        };
        taxCombo.setAllowBlank(false);
        taxCombo.hideAddButton();
        CellEditor taxComboCellEditor = new CellEditor(taxCombo);
        taxComboCellEditor.addListener(Events.Complete, new Listener<EditorEvent>() {
            @Override
            public void handleEvent(EditorEvent be) {
                /***************************************
                        HERE IS WHERE I NEED THE INVOLVED MODEL
                **********************************************/

            }
        });
        column = new ColumnConfig(getTaxIdentifier(), M.i.tax(), 70);
        column.setEditor(taxComboCellEditor);
        column.setRenderer(new GridCellRenderer<CHILD>() {
            public Object render(CHILD model, String property,
                    ColumnData config, int rowIndex, int colIndex,
                    ListStore<CHILD> store, Grid<CHILD> grid) {
                InvoiceTypeRow row = (InvoiceTypeRow) model;
                String taxName = "";
                if(null != row.getTax()) {
                    taxName = row.getTax().getName();
                }
                return taxName;
            }
        });
Thanks in advance
