You can create a simple PropertyModel to hold the value your form is
trying to set. Here is an example:
public Pageextends WebPage {
private List letters = Arrays.asList(new String[] {"A","B","C" }));
public String selected ="B";
public Page() {
Form form =new Form("form");
DropDownChoice choice=new DropDownChoice("ddc",new
PropertyModel(this,"selected"), letters);
}
}
The example is from:
https://cwiki.apache.org/WICKET/dropdownchoice-examples.html. It is
missing the generics if you are working in 1.4.x, but it demonstrates
the process well.
The model object here is the "selected" string. When the form saves
it will set the "selected" string with the value in the drop down.
Ah. I get it. Thank you Jered.
As a side question then, does this mean that the example cited in the
DropDownChoice javadoc does not work? Because it only did:
form.add(new DropDownChoice("site", SITES));
So wouldn't it fail the same way?
