Dropdown list in each row (J2EE track)

If someone wants to implement dropdown list in each row of the table, and he is using ADF BC in Model layer, there is no problem - just use ADF screencast available in Steve Muench blog. But, if TopLink and EJB are used in Model layer, then implementation will be little bit different. Below I describe how to implement this using TopLink and EJB.

Let us use standard HR schema entities - Employees and Departments. The main trick is to add getter and setter methods into Employees entity bean for the departmentId (this will enable us to use departmentId in Employees entity). Below are main steps you need to follow when developing View layer:

1. In the page definition file define methodAction for findAllDepartments. Define a methodIterator binded to findAllDepartments method definition and a table with two items - departmentId and departmentName
2. Create af:selectOneChoice in af:column component as it is described in Steve Muench screencast

So, the main differences are to modify entity bean and to define some additional elements in page definition file.
