JavaScript Access to currently selected item in <rich:listSh

[elridge]

Hello,

I hope this is the correct place this type of question.

I am using richfaces 3.1.5. I am trying to figure out how to access (via JavaScript) the currently selected item(s) in the source/target lists in the <rich:listShuttle > component?

As an example, I want to be able to fire a JavaScript reporting call onCopyClick in the listShuttle component. I do not know how (if it is possible) to access the selected item(s) from the source or target lists in JavaScript.

In the code example below, I wish to be able to make a call like:
oncopyclick="dcsMultiTrack('DCSext.dctag2','Columns','DCSext.dctag3', 'Add', 'DCSext.dctag4', '[currently selected item(s)]');"

I need to know with what to replace '[currently selected item(s)]' in the call above.

 <a4j:form id="tabcatColumnPicker">
 <rich:listShuttle sourceValue="#{toolBar.freeItems}"
 targetValue="#{toolBar.items}" var="items"
 sourceCaptionLabel="#{msgs.AvailableColumns}"
 targetCaptionLabel="#{msgs.CurrActiveColumns}"
 converter="listShuttleconverter" id="tabcatListShuttleColumns"
 copyControlLabel="#{msgs.Add}" copyAllControlLabel="#{msgs.AddAll}"
 removeControlLabel="#{msgs.Remove}"
 removeAllControlLabel="#{msgs.RemoveAll}"
 topControlLabel="#{msgs.Top}" upControlLabel="#{msgs.Up}"
 downControlLabel="#{msgs.Down}" bottomControlLabel="#{msgs.Bottom}"
 sourceListWidth="350" targetListWidth="350" listsHeight="250"
 oncopyallclick="dcsMultiTrack('DCSext.dctag2','Columns','DCSext.dctag3', 'Add All', 'DCSext.dctag4', 'None');"
 onremoveallclick="dcsMultiTrack('DCSext.dctag2','Columns','DCSext.dctag3', 'Remove All', 'DCSext.dctag4', 'None');"
 oncopyclick="dcsMultiTrack('DCSext.dctag2','Columns','DCSext.dctag3', 'Add', 'DCSext.dctag4', '[currently selected item(s)]');"
 >
 <rich:column>
 <h:outputText value="#{items.label}"></h:outputText>
 </rich:column>
 </rich:listShuttle>
 <a4j:commandButton value="#{msgs.Ok}" reRender="tabcatPageHeadingControlBar,tabcatFilterTable,tabcatFilterForm,tabcatColumnPickerPanel,tabcatNumResults,tabcatPagingTop,tabcatProductsTableForm,tabcatPagingBottom,niWdSimpleFeedbackForm" onclick="showLoadingMessage();"
 oncomplete="dcsMultiTrack('DCSext.dctag2','Columns','DCSext.dctag3', 'Selected Columns', 'DCSext.dctag4', '#{toolBar.itemsStr}'); hideLoadingMessage();" />
 </a4j:form>

Please Note: the data for the source and target lists is generated by use of a <rich:column> component within the <rich:listShuttle> component.

Is it even possible in this version of richfaces (3.1.5) to access the desired value via JavaScript? Any and all help would be appreciated!

Thanks,

Elridge
