listShuttel, Seam and @In

[pdpantages]

seam_version 2.0.1.GA
richfaces_version 3.1.4.GA

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}"
