Maybe I have found another solution using the standard AutoCompleteTextField
and a custom converter by overwriting getConverter():
public IConverter getConverter(final Class type) {
return new MyAutoCompleteConverter();
}
private class MyAutoCompleteConverter implements IConverter {
public MyDomainModelObject convertToObject(final String value, final
Locale
locale) {
if (Strings.isEmpty(value)) {
return null;
}
MyDomainModelObject myModelObject = findChoice(value);
if (myModelObject == null) {
try {
myModelObject = (MyDomainModelObject)
MyAutoCompleteTextField.this.getType().newInstance();
myModelObject.setValue(value);
} catch (Exception e) {
return null;
}
}
return myModelObject;
}
private MyDomainModelObject findChoice(final String value) {
MyDomainModelObject myChoice = null;
if (value != null) {
for (MyDomainModelObject choice : choices) {
if (choice.getValue() != null
&&
choice.getValue().equals(value)) {
myChoice = choice;
break;
}
}
}
return myChoice;
}
}
I do not need any special AjaxFormComponentUpdatingBehavior because the
findChoice() method is invoked from convertToObject(). I haven't tested it
enough but it seems to work.
Cheers,
Kai
