Activating form items with DISPLAY

Four Js Business Development Suite (BDS) allowed to enable/disable WIDGET="BUTTON", "CHECK" and "RADIO" fields of class "KEY" with the DISPLAY TO instruction:

DISPLAY "!" TO order.ord_status  -- Enables the field
DISPLAY "*" TO order.ord_status  -- Disables the field

With Genero BDS, use the DIALOG.setFieldActive() method to enable/disable fields, and the DIALOG.setActionActive() method to enable/disable actions (controlling form buttons). For more details, see Enabling and disabling actions
