>             Project: MyFaces Core
>          Issue Type: Bug
>          Components: JSR-252
>         Environment: tomcat 6, myfaces-1.2.1-SNAPSHOT (05 nov 2007)

> The following code:
>             <h:selectOneListbox id="si" binding="#{selectItemBean.component}" 
>                 value="#{selectItemBean.value}">
>                 <f:selectItems value="#{selectItemBean.list}"/>
>             </h:selectOneListbox>
> If the list is created as is:
>     public List<SelectItem> getList()
>     {
>         List<SelectItem> lista = new ArrayList<SelectItem>();
>         lista.add(new SelectItem(null, "NULL 2");
>         lista.add(new SelectItem("", "EMPTY"));
>         lista.add(new SelectItem("1", "Value 1"));
>         lista.add(new SelectItem("2", "Value 2"));
>         return lista;
>     }
> Render this:
> <select id="form:si" name="form:si" size="4">	
>    <option value="" selected="selected">NULL 2</option>	
>    <option value="" selected="selected">EMPTY</option>	
>    <option value="1">Value 1</option>	
>    <option value="2">Value 2</option>
> </select>
> null and empty String values are annotated equally.
> The problem is that JSF RI  assumes value="" as null when converting the value, but myfaces assumes empty String.
> The submited value is an empty String, decoded on JSF RI as null and on Myfaces as empty String. 
> JSF RI does not show this item as selected but set the value
> correctly to null. Myfaces sends a validation message "Validation Error: Value is not valid". 
> To be according to the spec, the preferred behavior is that JSF RI shows, so it's necessary a correction on myfaces to be compatible.
