Leonardo Uribe commented on MYFACES-3901:
-----------------------------------------

I have checked it and it looks like an spec issue. Mojarra also does not do anything with
f:selectItems and itemDescription. But taking a look at the renderkit spec javadoc of  javax.faces.SelectMany/javax.faces.Listbox
 in the section "Rendering the "option" elements" it says this:

"... If the current child is a UISelectItem create a SelectIteminstance from its itemValue,
itemLabel, itemEscaped, and itemDescription properties, add it to the list. If the current
child is a UISelectItems instance, call its getValue() method. If the result is a SelectItem
bean, add it to the list. If the result is an array of SelectItem beans, add each one to the
list. If the result is a Collection of SelectItem beans, add each one to the list. If the
result is a Map, create a SelectItem bean for each entry in the Map using the key as the label,
the value as the value, and null as the description. ..."

I tried pt:title with the latest snapshot and it works. I have created this issue to follow
this one:

https://java.net/jira/browse/JAVASERVERFACES_SPEC_PUBLIC-1285

I cannot fix it until get a response from the spec side about how this should work.

>             Project: MyFaces Core
>          Issue Type: Bug
>    Affects Versions: 2.2.3
>         Environment: java 7, tomcat 7
>            Reporter: Rene O
>            Priority: Minor

> I have a <h:selectOneListbox> with underlying List:
> {code}
> List<SelectItem> mylist = new ArrayList<SelectItem>();
> mylist.add(new SelectItem("testvalue", "testlabel","testdescription"));
> {code}
> I want to show a tooltip over any option of a selectbox.
> Therefore I tried two options:
> 1.
> {code}
> <h:selectOneListbox value="#{bean.myvalue}" ...>
> 	<f:selectItems value="#{bean.mylist}" var="item" itemValue="#{item.value}" itemLabel="#{item.label}"
itemDescription="yyy#{item.label}"/>
> </h:selectOneListbox>
> {code}
> 2.
> {code}
> <h:selectOneListbox value="#{bean.myvalue}" ...>
> 	<f:selectItems value="#{bean.mylist}" var="item" itemValue="#{item.value}" itemLabel="#{item.label}"
passtrough:title="yyy#{item.label}"/>
> </h:selectOneListbox>
> {code}
> Option 1 ignores itemDescription. Only label and value are rendered.
> Option 2 renders title attribute, but fills title only with "yyy" and ignores value of
#{item.label}
> I think, that this behaviour is a bug.
