Brian Leathem commented on RF-4308:
-----------------------------------
RichWidget issue [#137|https://github.com/richwidgets/richwidgets/issues/137]
has been resoloved; the client-side hook is now in place. Further work
required to resolve this issue involves:
# Extending
[ClientSelectItem|https://github.com/richfaces/richfaces/blob/master/framework/src/main/java/org/richfaces/ui/select/ClientSelectItem.java]
to track the sequence number of the Selectitem in the pick list
# Adding a _data-rf-index_ attribute to the items in the pick list [CDK
template|https://github.com/richfaces/richfaces/blob/master/framework/src/main/java/org/richfaces/ui/select/pickList/pick-list.template.xml]
# Adding a _sortFunction_ option to the pick-list widget invocation in the
[pick-list-bridge|https://github.com/richfaces/richfaces/blob/master/framework/src/main/resources/META-INF/resources/org.richfaces/bridge/select/pick-list-bridge.js]
----
In the mean time, a workaround would be to implement your own pick list widget
_sortFunction_ by listening for the widget _create_ event:
{code}
$('<my-selector>').on('picklist', 'create', function(a, b) {
return ...
});
{code}
A concrete example of this looks like:
{code}
$('#list').on('picklistcreate', function(event, ui) {
$('#list').pickList('option', 'sortFunction', function(a, b) {
return $(a).data('key') - $(b).data('key');
});
});
{code}
> rich:pickList: keep sort order of source list after add/remove operations
> -------------------------------------------------------------------------
>
> Key: RF-4308
> URL: https://issues.jboss.org/browse/RF-4308
> Project: RichFaces
> Issue Type: Feature Request
> Security Level: Public(Everyone can see)
> Affects Versions: 3.2.2
> Reporter: Martin Höller
> Labels: order, picklist, sort
> Fix For: 5-Tracking
>
>
> When adding items from the source list to the target list and removing this
> items again, the original order of the source list is not preserved. This
> makes it hard to find items in a list that is longer than just a fest items.
> A good example is the second example on the livedemo at
> http://livedemo.exadel.com/richfaces-demo/richfaces/pickList.jsf. Add the
> first state (Alabama) and remove it. It can now be found at the very end of
> the otherwise alphabetical list of states. This can be rather unintuitive for
> a user.
> My suggestion is either remember the original sort order of the source list,
> or add some attribute that enables automatic sorting.
