listShuttle 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 richfaces-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 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.

My backing bean is a SFSB, CONVERSATION scope.

Someone once posted a question asking if there was a limit on the
number of Seam components one may define.  This was never answered in
the forum. I have about 190, and thought I might be running into some
limit or something? I kind of doubt this, but I would like to take
this off the table as a possiblity.

Any other ideas as to what the problem might actually be would be
greatly appreciated, as I am completely stumped at this point.

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}"
   ...
