I used eclipse with Seam 2.0.0.GA and JBoss AS 4.2.2 and entity generated my code.  Tried to use S:convertEntity for a dropdown and received this error.  Could somebody help me with this issue?

Argument Error: An option for component prodxxx was not an instance of javax.faces.model.SelectItem. Type found: java.util.ArrayList.

<ui:define name="value1" required="true">
        <h:selectOneMenu id="prodxxx" required="true" value="#{projectHome.instance.product}">
            <f:selectItems value="#{productList.resultList}" var="product"
                        label="#{productList.product.prodSdescrip}"
                                noSelectionLabel="Select..."/>
            <s:convertEntity /> 
        </h:selectOneMenu>
        <a:support event="onblur" reRender="productDecoration" bypassUpdates="true" ajaxSingle="true"/>
</ui:define>
