the post is pretty confusing, i dont really understand what it is trying to solve/improve.
for an example of linked drop downs see [1], it is trivial to implement... [1] http://wicketstuff.org/wicket13/ajax/choice if on the other hand it is trying to render a map of key value pairs as opposed to an object that contains key and value as properties that is also trivial.... assuming class DropDownChoice<T> { DropDownChoice(String,IModel<T>, IModel<List<T>>, IChoiceRenderer<T> .... you can create class Pair<K,V> imlements Serializable { public K k; public V v; } class KeyValueDropDownChoice<K,V> extends DropDownChoice<Pair<K,V>> { public KeyValueDropDownChoice(String id, IModel<K> model, IModel<Map<K,V>> map) { super(id, model, new ChoicesModel(map), new ChoiceRenderer("k","v"); } // make sure drop down choice uses K as model value instead of Pair @Override public String getModelValue() { final Object id = getModelObject(); return (id==null) ? NO_SELECTION_VALUE : id.toString(); } private static class ChoicesModel extends LoadableDetachableModel { private final IModel<Map<K,V>> mapModel; public Object load() { Map<K,V> map=mapModel.getObject(); List<Pair<K,V>> choices=new ArrayList(map.size()); for (Entry e:map.entryset()) { choices.add(new Pair(e.key, e.value)); } return choices; } detach() { mapMode.detach(); super.detach(); } } looks like way less code to me for rendering key value pairs. but then again, like i said, dont really understand what that blog is trying to solve. -igor On Jan 1, 2008 11:24 PM, singhatulkr <[EMAIL PROTECTED]> wrote: > I came across this blog today:: > http://donteattoomuch.blogspot.com/2007/12/playing-with-wicketthe-component.html > It suggests some approach for drop-downs.. > ______________________________________ > Sent from my www.pageflakes.com startpage > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
