Renzo,
Sorry about that last post--I accidentally sent it
before I was done...
Anyway, let me send the real message:
In order to populate the list of selectable items from
your backing bean, you can use:
<f:selectItems value="#{backingBean.shuttleItems} />
The backingBean object should have a 'getShuttleItems'
accessor, which returns a: SelectItem[]. Each select
item may be an object-label pair, so there's where you
store your object reference. The value of the shuttle
component is an array of the objects (those which
appear in the object label pairs) that are currently
selected (on the right side of the shuttle).
For example, suppose the component on the page looks
like this:
<tr:selectManyShuttle
value="#{backingBean.selectedShuttleItems}">
<f:selectItems
value="#{backingBean.shuttleItems}" />
</tr:selectManyShuttle>
...and our backing bean looks like this:
(BackingBean.java)
...
//
// The list of selected items that should appear in
// the shuttle component.
//
Gizmo [] itemList = null;
//
// Returns the current selected objects.
//
Gizmo [] getSelectedShuttleItems()
{
}
//
//
//
...
public SelectItem[] getShuttleItems()
{
SelectItem[] shuttleItems = new SelectItem[ 3 ];
shuttleItems[ 0 ] = new SelectItem(
}
If you bind the shuttle component to a variable in the
backing bean, that component's value will be an array
of objects. For example, if getShuttleItems returns
an array of SelectItems, each

It's possible to achieve all of the behavior that you
describe without resorting to _javascript_.

Hi, I'm about to use these components, and I'm a
bit
confused about
their documentation.
Included demos provide list contents through
tr:selectItem children. At
the same time, I noticed that contents can be
get/set
through the
"value" attribute.
Can anybody enlight such usage ? Is there any
other
public demo/example
around ?
I also noticed that provided documentation refers
to
the chance of using
generic objects as list elements. This would be >
very
useful to append
further properties to list elements, to be managed
by
footer widgets
using provided js hooks on current selection. But
the
overall subject is
somewhat obscure.
Furthermore, I noticed that lists are always
provided
on the left
container only, where used has to move elements
rightwards. But I think
that common usage would start having some elements
already on the right
list (update mode). Is there any way to achive
this
initial setup - or
do I need to preprocess by means of js and a
hidden
"init" list?
Thanks -- Renzo
