I just tested and it worked. Thanks very much.
Pardon me for being stubbon here. For a simple
convertion like this, So much has to be created so it seems a little heavy
weight.
For this one,
first a subclass of Checkbox (possibly creating multiple constructors)
overide initmodel and separate custom model class just to convert
a simple data object to another. I'd still prefer the direct converter method.
Even though one could see it as in business domain, this kind of conversion
is generic enough to be put in the convert phase. Also, I saw you saying about
the detach() method, it could add some performance overhead, I guess.
Could you show me what I am doing wrong below for the converter method?
If this works, I'd even suggest to make it in the wicket core release:-)
by adding a method such as
new CheckBox(id).setTrueFalse("y","n"), you get the idea.
public class CheckBoxYN extends CheckBox{
public CheckBoxYN(String id){
super(id);
}
@Override
public final IConverter getConverter(Class arg0){
IConverter icYN = new IConverter(){
public Object convertToObject(String arg0, Locale arg1) {
if (arg0.equals("true")){
return 'Y';
}else{
return 'N';
}
}
public String convertToString(Object arg0, Locale arg1) {
if(arg0.toString().equals('Y')){
return "true";
}else{
return "false";
}
}
};
return icYN;
}
}
