display correct value in celleditor of RowEditorGrid

[currywurry]

Hi

In my grid, I display Car models. The model looks like:

private Integer vehicleId;
private Map<Integer, Driver> drivers

The drivers are displayed in the correct order (which is indicated by the key of the map), using a cell renderer, and this works fine (simplified):

public Object render(BeanModel model, String property, ColumnData config, int rowIndex, int colIndex,
ListStore<BeanModel> store, Grid<BeanModel> grid) {
Vehicle vehicle = model.getBean();
return vehicle.getDriverMap().get(colIndex).getName();
}

The problem however is, when doube-clicking the row to enable inline editing, the attached editor (a text field) is empty, because GXT can't resolve the correct driver from the the drivermap. Is there a way to do this anyway, or can't beanmodels contain collections? This is a problem, as the number of drivers varies.

thanks for your help

Try this.

TextField<String> text = new TextField<String>();
text.setAllowBlank(false);
column.setEditor(new CellEditor(text) {
   @Override
   public Object preProcessValue(Object value) { 
      BeanModel model = store.getAt(row);
      Vehicle vehicle = model.getBean();
      return vehicle.getDriverMap().get(col).getName();
   }

   @Override
   public Object postProcessValue(Object value) {
      BeanModel model = store.getAt(row);
      Vehicle vehicle = model.getBean();
      vehicle.getDriverMap().get(col).setName((String)value);
      store.update(model);
      this.cancelEdit();
      return null;
   }
});
