How can I get the value from s:selectItems

[chicochen]

Why devIds always is null? thanks.


Webpage:

<h:selectManyListbox value="#{devIds}" size="8" >
 <s:selectItems value="#{devListForAdd}" var="dev" label="#{dev.englishName}"/>
 <s:convertEntity />
 </h:selectManyListbox>

Action:

<s:button action="#{actorDevMaintAction.saveDev}"
 value="Add" />

@In(required = false)
 @Out(required=false)
 private List<User> devIds;
