How to dynamically create a <f:selectItem> list?

问题

Is there a way to dynamically create a selectItem list? I dont really want to have to create lots of bean code to make my lists return List<SelectItem>.

I tried this:

<ice:selectManyCheckbox>
    <ui:repeat var="product" value="#{productListingService.list}">
      <f:selectItem itemLabel="#{product.description}" value="#{product.id}"/>
    </ui:repeat>
</ice:selectManyCheckbox>

but it doesnt work.

Any ideas?

回答1:

Use <f:selectItems> instead. It accepts next to List<SelectItem> and SelectItem[] also a Map<String, Object> as value where the map key is the item label and map value is the item value. Or if you're already on JSF 2.0, then you can use a List<SomeBean> instead where the current item can be referenced by the var attribute.

<f:selectItems value="#{productListingService.list}" var="product" 
    itemLabel="#{product.description}" itemValue="#{product.id}" />
