Hi Nick

I would like to know how you are accessing rolePickList in your backing bean.  I have a similar thing defined in my application.  And I  have getters and setters for the pickList in my backing bean.  Now when I hit update button on the page, a  backing bean method updateCourseOffr() is invoked.  Within that method, I try to print the size of the pickList, and I get 0.  I am able to populate the left pickList.  I am talking about accessing the right picked List.

Please let me know if you have any suggestion for it.

thanks
Sai

> 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).
