Brendan Farragher updated RF-6862:
----------------------------------
Attachment: TestRichFacesPicklistWithoutBinding.tar
TestRichFacesPicklistWithBinding.tar
I tried two variations with the ajaxSingle="true" attribute added to the
a4j:support tag, but neither one worked for me. The first variation tried to
reRender an a4j:outputPanel that wraps the picklist, and the other just tries a
straight re-rendering of the picklist itself (you'll see one version commented
out in the jsp).
I am attaching my test applications (exported from RHDS as Eclipse archive
files, compressed, and in .tar format). The "WithoutBinding" version does not
work. The "WithBinding" version is functional, and contains the workaround that
I have described.
I also receive an UnsupportedOperationException in the "WithoutBinding" version
when I select from the selectonelistbox the *second* time. This is probably due
to the fact that I need to clear the select items (target) list when the
selectonelistbox selection changes.
Thank you.

> Key: RF-6862
> URL: https://jira.jboss.org/jira/browse/RF-6862
> Project: RichFaces
> Issue Type: Bug
> Affects Versions: 3.2.2, 3.3.0
> Environment: JBoss AS 4.2.3 (Ubuntu Linux 8.04)
> Reporter: Brendan Farragher
> Attachments: TestRichFacesPicklistWithBinding.tar,
> TestRichFacesPicklistWithoutBinding.tar

> The RichFaces picklist component does not re-load it's pre-selected (target)
> data correctly when an onchange event of a dependent selectonelistbox
> component is raised. If a valuechangelistener method is set on the
> selectonelistbox, and that method loads the picklist's source and target
> lists with new data, the target list is not populated when the page is
> re-displayed (in this case, the target list in the backing bean maps to the
> value attribute of the picklist tag). I even tried wrapping the picklist in
> an a4j:outputPanel with an a4j:support event=onchange reRender=pickListName
> tag placed inside of the selectonelistbox tag, but the target list is never
> populated.
> I have a JSF test application developed that I can provide you with that
> demonstrates the problem, and a second JSF test application that contains a
> workaround using a bound HtmlPickList (the workaround is not really
> appropriate for Seam integration, though). (Please update the JIRA with a
> forwarding address if you would like my test apps)
> Please note that this bug has more important implications for Seam
> integration, since JSF component binding is discouraged. As a result, the
> value attribute of the picklist (the target data) needs to be refreshed via
> the picklist tag value attribute (or via some a4j help).
