    ClassCastException in PickListUtils.findUISelectManyConverte

    infinity2heaven Novice

      I'm trying to use rich:picklist

      <h:panelGrid title="Fund of Funds" border="0" cellpadding="5">
       <rich:pickList value="#{selectededFof.funds}">
       <f:selectItems value="#{fundsQuery.resultList}"/>
       <a4j:support event="onlistchanged" reRender="result"/>
       </rich:pickList>
       <rich:panel id="result" bodyClass="pbody">
       <f:facet name="header">
       <rich:dataList value="#{selectededFof.funds}" var="fund" rendered="#{selectededFof.funds > 0}">
       <h:outputText value="#{fund.name}"/>
       </rich:dataList>
       </f:facet>
       </rich:panel>
       <a4j:commandButton value="Update" action="#{fofAdmin.update}"
       styleClass="buttonRight" reRender="fofFundsTable" />
      </h:panelGrid>


      and I get a class cast exception

      java.lang.ClassCastException: xxx.entity.Fund
