为什么 f:selectItems 不允许我添加另一个值？ JBOSS/JSF

Question

I have the following code:

<ui:repeat var="_shipment"
value="#{_order.orderShipmentList}">
<h:selectOneMenu value="#{_shipment.shipmentMethodCode.id}">
    <f:selectItems id="selectShipList"
        value="#{consoleContext.shipmentMethods}" />
</h:selectOneMenu>
</ui:repeat>

In the f:selectItems value attribute I want to add #{_shipment.shipmentMethodCode.id} - #{consoleContext.shipmentMethods}

SO it would read 1 - Standard Shipping

But I get an error: Expected a child component type of UISelectItem/UISelectItems for component type javax.faces.SelectOne(j_id58). Found java.lang.String.

Answer 1

The value attribute should point to a collection of Javabeans or SelectItem objects, not to strings.

If you don't/can't change it in the Javabean or SelectItem side, then you need the to use itemLabel attribute instead.

<f:selectItems id="selectShipList" value="#{consoleContext.shipmentMethods}" var="shipmentMethod" 
    itemValue="#{shipmentMethod.id}" itemLabel="#{shipmentMethod.id} - #{shipmentMethod.name}" />
