[visumagic]

Hi

I'm trying to implement listShuttle.I'm using seam 2.1.1 cr2

  <rich:listShuttle id="myList" 
              
            sourceValue="#{courseBrancheList}"
            targetValue="#{CollegeReg.selectedCourseBrancheList}"
               converter="org.jboss.seam.ui.EntityConverter"
               fastOrderControlsVisible="false"
               
               var="i"
               orderControlsVisible="false"
               sourceCaptionLabel="Source List" targetCaptionLabel="Target List">
               
                 <rich:column>
                <h:outputText value="#{i.id}"/>
            </rich:column>
           
           
            </rich:listShuttle>

And I'm getting following exception, and because of this im not able to submit the form values.

00:59:32,296 INFO  [lifecycle] WARNING: FacesMessage(s) have been enqueued, but may not have been displayed.

Have you had any success with the above issue?

[visumagic]

Yes .. I faced this issue long time back ..
I'm able to fix this..

I was using query.resultList directly which is not writable
I got a mid-factory to host the source shuffled values.
