Leonid Sokolin commented on RF-6596:
------------------------------------

I have similar problem using a combo box. I want to populate combo box with list of values selected in shuttleList.

I have the following shuttleList:

<rich:listShuttle id="selectTimePeriods" sourceValue="#{qtBeanParam.allTrailingPeriods}"
		            targetValue="#{qtBeanParam.selectedTrailingPeriods}" var="itemTime" 
		            listsHeight="150"
		            sourceListWidth="150" sourceCaptionLabel="Available Trailing Periods"
		            targetListWidth="150" targetCaptionLabel="Selected Trailing Periods"
		            targetRequired="true" requiredMessage="Periods should be selected."
		            copyAllControlLabel="" copyControlLabel="" removeAllControlLabel="" removeControlLabel=""
		            upControlLabel="" topControlLabel="" downControlLabel="" bottomControlLabel=""
		            >
		            <rich:column width="120">
		                <h:outputText value="#{itemTime.display}"></h:outputText>
		            </rich:column>
		            <a4j:support event="onlistchanged" reRender="sortPeriod,sortPeriodList" ajaxSingle="true"/>
		        </rich:listShuttle>

and put the following in dependent combo box:

<rich:comboBox id="sortPeriod" width="100" value="#{qtBeanParam.sortPeriod}" >
<f:selectItems id="sortPeriodList" value="#{qtBeanParam.selectedTrailingPeriods}" />
</rich:comboBox>

Problem is that values selected in the shuttleList are enums:

public enum TrailingPeriods {
	MostRecentMonth(1,"MRM"), MostRecentQuarter(3,"MRQ"), SixMonths(6, "6 M"), YearToDate(-1, "YTD"), OneYear(12, "1 Yr"), 
	TwoYear(2*12, "2 Yrs"), ThreeYear(3*12, "3 Yrs"), FourYear(4*12, "4 Yrs"), FiveYear(5*12, "5 Yrs"), 
	SixYear(6*12, "6 Yrs"), SevenYear(7*12, "7 Yrs"), EightYear(8*12, "8 Yrs"), NineYear(9*12, "9 Yrs"), 
	TenYear(10*12, "10 Yrs"), SinceInception(-10, "Since Inception");
...

And it throws cast exception when shuttleList is changed:

17:22:48,656 ERROR [[Faces Servlet]] Servlet.service() for servlet Faces Servlet threw exception
java.lang.ClassCastException: com.nb.pi.processor.beans.TrailingPeriods
	at org.richfaces.renderkit.ComboBoxBaseRenderer.encodeItems(ComboBoxBaseRenderer.java:96)
	at org.richfaces.renderkit.html.ComboBoxRenderer.doEncodeEnd(ComboBoxRenderer.java:558)
	at org.richfaces.renderkit.html.ComboBoxRenderer.doEncodeEnd(ComboBoxRenderer.java:587)
	at org.ajax4jsf.renderkit.RendererBase.encodeEnd(RendererBase.java:134)
	at javax.faces.component.UIComponentBase.encodeEnd(UIComponentBase.java:836)
...

Does it mean that I coudn;t use enums here?
