Re: DropDownChoice ID's
I was missing the fact the values are looked up. Your right, I do not care
if the values are 1,2,3... as long as I get the right stuff in my Model

Re: DropDownChoice ID's
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

Re: DropDownChoice ID's
After changing genders from ListGender to ListString, 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
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.

Not sure what I'm doing wrong. I need a DropDownChoice with ...
option value=fFemale/option
option value=mMale/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.gen...@30ea3e3c

List test = Arrays.asList(new String[] { A, B, C });

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.

Re: DropDownChoice ID's
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();
}
}
