 Hi Martin

 But the DDC doesn't have a constructor with PropertyModel[String](this,

 only a property model with the Object/Pojo as I was using.


String is an Object, no ? ;-)

You need to read some more on Java generics.
There is nothing more you need to understand this problem.


 good examples around

  The way you already did it will set the selected value in customer's
 name.
  Check PropertyModel's javadoc to understand how it works.
 
  If you want to read/write the value in 'custName' then you have to use:
 new
  PropertyModel[String](this, custName)
 
 
   Thanks very much for help me.

Martin, the DDC has already created with the sema object type in the
constructor
for PropertyModel, listCustomer, and ChoiceRenderer

new DropDownChoice(customerSelection,
new PropertyModel[Customer](customer, name), listCustomer, new
ChoiceRenderer[Customer](name))*

But I need only a piece of code that works in retrieve the selected value.

Thanks again.

You should have objects of same type in DropDownChoice, PropertyModel, List
and ChoiceRenderer
