Auto complete filed problem

[Renju]

Dear All,
My primefaces version is primefaces-2.2.1 and jsf version is 2.0.3. I have one autocomplete filed in my page and its giving all the suggessions correctly. But when I submit the form, I am getting null value for the selected object.

<p:autoComplete value="#{newTaskBean.selectedRelatedProject}"
completeMethod="#{newTaskBean.completeProject}"
var="project" itemLabel="#{project.nameEn}"
itemValue="#{lookupVO}" converter="projectConverter"/>

There is a class called lookupVO which has nameEn, id as fileds. selectedRelatedProject ia a list of this class obects. In the bean when I print selectedRelatedProject.getNameEn(), its printing null.

Thanks and Regards,
Renju
