    RichFaces ShuttleList sample doesn't work in a Seam framewor

    Todd Nash Newbie

      In an effort to validate the errors with the ShuttleList in my own pages, I decided to see if the sample works in a Seam framework.

      I have found that many of the Richfaces components don't work well when used in a Seam framework. Are you guys testing anything using Seam?

      I only modified the sample code enough to avoid any Seam errors. Specifically, I had to remove the UIEventsBouncer because org.ajax4jsf.component.UIDataAdaptor doesn't exist in the Richfaces jars and you can't include the ajax4jsf jars when using Seam.

      The following error occurs in both 3.1.3 and 3.1.4.

      When I click the submit button on the page containing a ListShuttle I get the following error:

      javax.el.PropertyNotFoundException: /documents/listShuttle.xhtml @52,55 value="#{item.name}": Property 'name' not found on type java.lang.String

      Here is the xhtml page I modified from the samples:
