-====== Bank Advisers Sample ====== +====== Bank Advisers ====== 
-...+ 
 +**Bank Advisers** is a [[SOLoist Sample Applications|SOLoist sample application]] that combines several features presented in the previous examples, most notably [[Edit Person's Details|Edit Object Details]], [[Person Tables|Grids]], [[Persons and Bank Accounts|CRUD]], and [[Association Editor|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//.
