Bank Advisers

Bank Advisers is a SOLoist sample application that combines several features presented in the previous examples, most notably Edit Object Details, Grids, CRUD, and Selection List.

All objects of the class BankAdviser are shown in a grid. Attribute slots of these objects can be edited in the grid fields.

Objects of the class BankAdviser can be created or deleted with the command buttons.

Selecting one Bank Adviser from the grid will enable the checkbox editor in the Clients list. Ticking a checkbox next to a Person object in the list will make that person a client of the selected Bank Adviser.
