I am trying to add an a4j:support onclick event to a listShuttle. Everything seems to work fine until I use the copy button for the first time. Then whenever I click on anything again in the listShuttle I get the following error in my log file.

Component profileBuilderForm:listShuttleChooseNewProfileItems has invalid value expression null

Here is my form that is giving me problems.

<h:form id="profileBuilderForm" styleClass="formNoPadding">
 <a4j:commandButton id="retrievePossibleProfileItemsButton"
 value="#{msg.goButtonLabel}"
 action="#{profileBuilderBean.retrievePossibleProfileItems}"
 disabled="#{profileBuilderBean.working}"
 reRender="profilePanelPhase1"/>
 <hr/>

 <h:panelGroup id="profilePanelPhase1" style="#{profileBuilderBean.profilePhase1Style}">
 <h:panelGrid id="orderingGrid" columns="2" columnClasses="leftInfoCol, rightInfoCol">
 <rich:listShuttle id="listShuttleChooseNewProfileItems"
 sourceValue="#{profileBuilderBean.sourceItems}"
 targetValue="#{profileBuilderBean.targetItems}" var="items"
 sourceSelection="#{profileBuilderBean.sourceSelection}"
 sourceListWidth="250" listsHeight="250" targetListWidth="250"
 sourceCaptionLabel="Available Items"
 targetCaptionLabel="Currently Active Items"
 converter="correctedAudioItemConverter"
 fastOrderControlsVisible="false"
 orderControlsVisible="false">

 <rich:column>
 <h:outputText id="itemIdValue" value="#{items.itemId}"></h:outputText>
 </rich:column>
 <rich:column>
 <h:outputText id="itemWordCountText" value="#{items.wordCount}"></h:outputText>
 </rich:column>

 <a4j:support event="onclick" reRender="profileAddSelectOutput"/>
 </rich:listShuttle>

 <rich:panel id="profileAddSelectOutput" header="#{msg.currentSelection}"
 style="display: #{!empty profileBuilderBean.sourceSelection ? '' : 'none'}">
 <h:outputText id="testText" value="Hello I have values"/>
 </rich:panel>
 </h:panelGrid>
 </h:panelGroup>
</h:form>

My goal is to make it so when the user choose something on the source side of the listShuttle the details of that item are displayed in a panel to the right of the listShuttle, kinda how the orderingList demo works in the live demo.

Any help would be appreciated.
