I have a grid with different columns which values map into POJO object via ValueProperties interface. Now I would like to add one column which value is really calculate by application state + some bean states. How can I create ValueProperties method to get values if I don't have this calculate values in my bean? This was very easy in GXT 2.x :

GridCellRenderer<BaseModelData> buttonRenderer = new GridCellRenderer<BaseModelData>() {
public Object render(final BaseModelData model, String property, ColumnData config, final int rowIndex, final int colIndex, ListStore<BaseModelData> store, Grid<BaseModelData> grid) {

Thank you for advice.
