ui:repeat doesn't work with f:selectItem

Question

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 1

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.

it gives me an exception, that the property name doesn't exist in UserBean !!!!!!!! why it thinks that the list is of type UserBean not User ?????? – Butene

Can you please tone a bit down? I gather that you're talking about a PropertyNotFoundException on usersList? Well, then that means that you don't have a public List<User> getUsersList() method in the backing bean class represented by the #{user} managed bean. – Inellineloquent

Oh, you are not using JSF managed beans, but you are using Spring managed beans (you didn't tell/tag anything about this in your question, so I couldn't forsee it). Well, then use #{user.getUsersList()} if standard EL call is not possible (I don't use Spring, so I can't tell if this is indeed true). You have by the way a syntax error in your class; Public is an invalid keyword, it should be public. – Inellineloquent

even when using #{user.getUsersList()} i keep getting same error. – Butene

ah found it, the var name in loop was matching the ManagedBean name: @Component("user") , it was fixed by changing the var name. – Butene

Yes, you're right. That would conflict. I updated the answer to reflect that as well. – Inellineloquent

any ideas how to get the Selected Users in such case ? – Butene

This is offtopic. Ask a new question. Hint: <ice:selectOneMenu value>. – Inellineloquent

Answer 2

why not use f:selectItems. I think something like this would work.

<f:selectItems value="#{user.getUsersList()}" var="user" itemLabel="#{user.name}"
                                            itemValue="#{user.id}" />

EDIT also try removing the brackets from the user.getUsersList() in your code , i think its not how you call a function in jsf2

Upshaw

As per your edit, this is valid in EL 2.2, but plain clumsy if it's just a simple getter. – Inellineloquent
