New Component
After long time, I'm decide to create a custom component. :P
I want to do a component like ShuttleList of ADF, Two SelectManyListBox,
four CommandButtons (Add, Add All, Remove, Remove All). The elements inside
Lists can move together Lists.
My cuestion is... can extends an existent UIComponent to do this or... I
extends of UIComponent Class :(?
How think is the better mode to do this component? :)
Thanxs!!!

I also can recommend Kitos book, I think the appendix example components
are the best introductions you can get into component building currntly.
And yes, SelectMany might be a good headstart as well.
Anything higher than UIComponent pretty much is a better start than
UIComponent itself.

I personally think subclassing UISelectMany would be the best way, because
you have to deal with all the converter stuff and the result is similar to
a UISelectMany component. But it depends on what requirements you have.
You can also create subcomponents by code and/or use an existing render of
standard components (at Renderer interface level). This explained by KITO
D. MANN in the online appendix of "JavaServer Faces in Action".

If you output only HTML then you can use HtmlSelectManyListbox.
If it's posssible to use only methods provided by UISelectMany, then use
the superclass instead. But you have to make sure that the Listbox
renderer is used by the component.

I define this Class... but I have a dude...
The two list inside of this Class... must be HtmlSelectManyListBox or
UISelectMany ?
public class HtmlShuttleList extends UIPanel {
public static final String SHUTTLE_LIST_FAMILY = "SLFAMILY";
HtmlSelectManyListbox validList;
HtmlSelectManyListbox selectedList;
HtmlCommandButton addButton, addAllButton, removeButton,
removeAllButton;

Hi Mariano, the best way to do this is to find a component which does
most of the wanted functionality and then write a child class of the
tag, the renderer and the component (if needed)
You can use UIComponent as a base, but you will save lots of work if you
start with a more high level approach (Most components derive from
something higher than UIComponent or UIInput)
For the ShuttleList a Panel or a Div might be a good starting point as a
base because you need some kind of Panel Functionality anway.
