JSF component

Question

i want to make simple DropDownList.

<p:selectOneMenu id="starter" value="#{reportRegisterManagedBean.starter}" style="width:160px" converter="#{reportStarterConverter}" required="true" requiredMessage="Select Report Starter">
                           <ui:repeat value="#{reportRegisterManagedBean.startersSelectItems}" var="dss">
                                <f:selectItem  itemLabel="#{dss}" itemValue="#{dss}" itemDescription="TEST" />
                           </ui:repeat>
                        </p:selectOneMenu>

DropDownList is enpty, if i use <f:selectItems> instead of <ui:repeat> works very well, but <f:selectItems> Component itemDescription=(this is simple tooltip analogy) not working. <f:selectItem> Component itemDescription=(this is simple tooltip analogy) working fine. That's why I decided to use the and <f:selectItem> with its itemDescription attribute.

Which field contains the list that you want to display in the DropDownList ? `reportRegisterManagedBean.starter` or `reportRegisterManagedBean.startersSelectItems` ? — Apurv, Mar 29 '13 at 09:21
reportRegisterManagedBean.starter is one component. reportRegisterManagedBean.startersSelectItems is list off reportRegisterManagedBean.starter components — zura katsitadze, Mar 29 '13 at 09:36

why do you want to use ui:repeat? post your bean code reportRegisterManagedBean.startersSelectItems — roel, Mar 29 '13 at 10:07
Because, here itemDescription="TEST" (tooltip) works and itemDescription="#{ds.name}" now working here. — zura katsitadze, Mar 29 '13 at 11:42

The <f:selectItem> needs to be added during view build time. However, the <ui:repeat> runs during view render time. You need a repeater which runs during view build time. The JSTL <c:forEach> is such one.

<p:selectOneMenu ...>
    <c:forEach items="#{reportRegisterManagedBean.startersSelectItems}" var="dss">
        <f:selectItem ... />
    </c:forEach>
</p:selectOneMenu>

Alternatively, create a custom renderer. Here's an example which does exactly the same for <p:selectManyCheckbox>: Primefaces tooltip for p:selectManyCheckbox

As you don't like String array. here is tested and working example with User class:

public class FilterBean {

private List<User> uList = new ArrayList<User>();
private User selectedUser = new User();


public List<User> getuList() {
    User u1 = new User();
    u1.setName("Tom");
    u1.setDesc("worker");
    User u2 = new User();
    u2.setName("Peter");
    u2.setDesc("owner");

    uList.add(u1);
    uList.add(u2);

    return uList;
}

public void setuList(List<User> uList) {
    this.uList = uList;
}   

public User getSelectedUser() {
    return selectedUser;
}

public void setSelectedUser(User selectedUser) {
    this.selectedUser = selectedUser;
}
}

And this is JSF

    <p:selectOneMenu value="#{filterBean.selectedUser}"> 
        <f:selectItem itemLabel="Select One" itemValue="" />   
        <f:selectItems  value="#{filterBean.uList}" var="n" itemValue="#{n}" itemDescription="#{n.desc}" itemLabel="#{n.name}" />  
    </p:selectOneMenu>

This shows desc for Tom and Peter :)

Here is how you create a drop-down list in primefaces:

<p:selectOneMenu id="starter" value="#{reportRegisterManagedBean.starter.selectedItem}">  
        <f:selectItems value="#{reportRegisterManagedBean.starter.startersSelectItems}" />  
</p:selectOneMenu>

this works but component itemDescription="" not working, and itemDescription="" works, That's why I decided to use the and with its itemDescription attribute. – zura katsitadze Mar 29 '13 at 09:39
When `itemDescription` is used with `f:selectItems`, it needs a `List`. [This](http://stackoverflow.com/a/15609873/960778) has a solution for your problem – Apurv Mar 29 '13 at 09:48
public List startersSelectItems; this is list – zura katsitadze Mar 29 '13 at 09:53

I have tried several examples and got this results:

I have this in pojo:

private String selectL;
private String[] listas;


public String[] getListas() {
    listas = new String[2];  
    listas[0] = "pirmas";
    listas[1] = "antras";
    return listas;
}

and this jsf works (itemDescription must be String):

    <p:selectOneMenu value="#{formBean.selectL}">   
        <f:selectItems  value="#{filterBean.listas}" var="n" itemDescription="#{n}2" />  
    </p:selectOneMenu>

and this not :/ :

    <p:selectOneMenu value="#{formBean.selectL}">   
        <f:selectItems  value="#{filterBean.listas}" itemDescription="test2" />  
    </p:selectOneMenu>

EDIT:

After some test I just added var into second selectOneMenu and it WORKS now too:

    <p:selectOneMenu value="#{formBean.selectL}">   
        <f:selectItems  value="#{filterBean.listas}" var="n" itemDescription="test2" />  
    </p:selectOneMenu>

itemDescription="test2" this works well? i want to dinamically tooltip, e.i. #{ds.name} and #{ds.description} and this is realized only SelectItem in list – zura katsitadze Mar 29 '13 at 13:43
for me itemDescription="#{n}2" and itemDescription="test2" works fine now. Tested on IE, FF and chome. – Darka Mar 29 '13 at 13:47
ok, but i want to list, because in my list i have put hibernate entity, and how to put entity in String array, this is bad idea – zura katsitadze Mar 29 '13 at 13:53
I dont think u need to put this into String array. This is just example. Just this ds.name should be as String. – Darka Mar 29 '13 at 13:58
