    listShuttel, Seam and @In

      Hello Forum,

      I have an odd problem with listShuttle, when I use @In/Out on the value of
      the sourceValue. I am going to cross-post this to seam-users forum also.

      When moving values back from the targetValue to sourceValue, I would get
      a validation error something like this:

      2008-04-07 18:59:13,399 INFO [http-0.0.0.0-8080-1] javax.enterprise.resource.webcontainer.jsf.lifecycle
      WARNING: FacesMessage(s) have been enqueued, but may not have been displayed.
      sourceId=j_id30:j_id286[severity=(ERROR 2), summary=(j_id30:j_id286: Validation Error: Value All is not valid), detail=(j_id30:j_id286: Validation Error: Value All is not valid)]
      



      The symptoms are similar to that of an ealier posting (mine) but the root
      problem is different:

      The root of it all was that, when I submit my form, richfaces fails to
      write the value of sourceValue. I verified this by putting
      printlns in the setter for sourceValue, and I can see that ths setter is not called
      when the form is submitted.

      However, if I drop the @In/@Out and just use conventional getter/setter
      in my @Local interface, the problem goes away.

      The thing is, I have other listShuttle objects, where I use @Out/In w/o any problems.
      I cannot find any difference between the implementation of this and the other cases.
      Believe me, I looked.

      Any ideas as to what the problem might actually be would be greatly appreciated, as I am completely stumped at this point. I asked the seam-forum if there is a limit on the number of seam components one may have, but I am doubtful that there is.

      Original Code: (doesn't work)

      
      BEAN:
      
      @In(required=false)
      @Out
      private List<AlarmSuppressionPolicy> availableAlarmSuppressionPolicies;
      
      Xhtml:
      
      <rich:listShuttle
       sourceValue="#{availableAlarmSuppressionPolicies}"
       targetValue="#{serviceEntry.alarmSuppressionPolicies}"
       var="row"
       listClass="scroll_container"
       sourceCaptionLabel="Available Policies"
       targetCaptionLabel="Enforced Policies"
       removeAllControlLabel="Remove all policies"
       removeControlLabel="Remove policy"
       copyControlLabel="Add policy"
       copyAllControlLabel="Add all policies"
       listsHeight="30em"
       sourceListWidth="45em"
       targetListWidth="45em"
       converter="#{availableAlarmSuppressionPolicyMgmt.alarmSuppressionPolicyConverter}">
      
       <rich:column sortable="false">
      
       <f:facet name="header">
       <h:outputText
       class="sortLink"
       value="Name"/>
       </f:facet>
      
       <h:outputText value="#{row['name']}"/>
      
       </rich:column>
      
      </rich:listShuttle>
      
      


      New Code (works)

      
      BEAN:
       public List<AlarmSuppressionPolicy> getAlarmSuppressionPolicies() {
       return this.alarmSuppressionPolicies;
       }
      
       public void setAlarmSuppressionPolicies( List<AlarmSuppressionPolicy> alarmSuppressionPolicies ) {
       this.alarmSuppressionPolicies = alarmSuppressionPolicies;
       }
      
      Xhtml:
      
       ...
       sourceValue="#{availableAlarmSuppressionPolicyMgmt.alarmSuppressionPolicies}"
       ...
