DropDownChoice ID's
List test = Arrays.asList(new String[] { "A", "B", "C" });
add(new DropDownChoice("test", test));
How can I make the Id's match the Values? There coming through as
1,2,3. I've tried custom ChoiceRenderer, but seem to be missing something.
Any help is appreciated.

Think I figured it out by doing something like this. Is this the right way?
public class StringChoiceRender implements IChoiceRenderer {
public Object getDisplayValue(Object object) {
return object.toString();
}
public String getIdValue(Object object, int index) {
return object.toString();
}
}

I was missing the fact the values are looked up. Your right, I do not care

Why do you care what the id's are? Wicket doesn't store the ID anywhere,
it just uses the ID to look up the list element to put into the model.

Re: DropDownChoice ID's
Posted by Oblivian <ch...@carlsoncentral.com>.
After changing genders from List<Gender> to List<String>, I'm seeing the
opposite behaviour. The values are coming across as ['m','f'] but the id's
are ['0','1']
Overriding getIdValues() instead of getDisplayValues() seems to work.

Re: DropDownChoice ID's
Posted by John Krasnay <jo...@krasnay.ca>.
The golden rule of DropDownChoice is that the values in the list must be
the same as the property you are trying to set. In your case, if you
want basicDemographicInfo.gender to be set to "m" or "f", you must pass
the DropDownChoice the list [ "m", "f" ]. You'll then need a renderer
that produces the appropriate display value:
new ChoiceRender() {
public Object getDisplayValue(Object value) {
// here, value will be "m" or "f"
// look up and return "Male" or "Female" accordingly
}
}
You shouldn't care about the ID value. The default provided by
ChoiceRenderer should be fine.

Re: DropDownChoice ID's
Posted by Oblivian <ch...@carlsoncentral.com>.
Not sure what I'm doing wrong. I need a DropDownChoice with ...
<option value="f">Female</option>
<option value="m">Male</option>
have a basic class like this ...
public class Gender implements Serializable {
String id;
String name;
public Gender();
public Gender(String id, String name);
public String getId();
public void setId(String id);
public void setName(String name);
}
A custom ChoiceRenderer ...
public class GenderChoiceRenderer implements IChoiceRenderer {
public Object getDisplayValue(Object arg0) {
return ((Gender) arg0).getName();
}
public String getIdValue(Object arg0, int arg1) {
// Sometimes this is a String
if(arg0 instanceof String){
return (String)arg0;
}
if (Utility.isNull(arg0)){
return null;
}
// Other times it is not.
return ((Gender) arg0).getId();
}
}
----------
Finally in my Form...
add(new DropDownChoice("gender", new PropertyModel(model,
"basicDemographicInfo.gender"), genders, new GenderChoiceRender()));
Viewing the HTML, the id's are correct "m" and "f", however in onSubmit, I
get this.
model.getBasicDemographicInfo().getGender() =
com.spinn.sdk.db.model.Gender@30ea3e3c
