ui:repeat doesn't work with f:selectItem
i am using icefaces select on menu to select a user from list of users and i want to repeat the selectItem for each user here's what i tried:
<ice:selectOneMenu id="users">
<ui:repeat value="#{user.getUserList()}" var="user">
<f:selectItem itemLabel="#{user.name}" itemValue="#{user.id}"/>
</ui:repeat>
</ice:selectOneMenu>
UserBean:
@Component("user")
@Scope("view")
Public class UserBean{
Public List<User> getUserList() throws Exception {
return userService.getAllUsers();
}
}
NOTE: UserBean doesn't contains the properties id,name they exist in User entity. please advise, thanks.
Answer
The <ui:repeat> is an UI component while <f:selectItem> is a taghandler (like JSTL). Taghandlers runs during view build time before UI components which runs during view render time. So at the moment the <ui:repeat> runs, there is no means of a <f:selectItem>.
A <c:forEach>, which is also a tag handler, would work, but much better is to use <f:selectItems> instead. Since JSF 2.0 it can take a collection and support the var attribute as well:
<ice:selectOneMenu id="users">
<f:selectItems value="#{user.usersList}" var="userItem"
itemLabel="#{userItem.name}" itemValue="#{userItem.id}" />
</ice:selectOneMenu>
Note that the var attribute should not clash with an existing bean in the scope.
