UsersByDepartmentSelectionModel.java (and
DepartmentSelectionModel.jav)
looks suspcious.
The UsersByDepartmentSelectionModel.getOption method
returns a value
from userLists, but
UsersByDepartmentSelectionModel.translateValue returns
a value using a dao.
You might like to test
UsersByDepartmentSelectionModel in a standalone
PropertySelection
component : select an entry from the drop list. Print
the selected value in a form
listener method.
