SelectItems + IllegalArgumentException + help

[Mansingh Shitole]

I am facing the problem, whenever I am trying to write selectItems tag in SelectOneMenu parent tag, it occurs. I am unable to find out why this illegalArgumentException is coming. Although value is coming in the list. But when Iam submitting the form it is giving exception. I am creating List of SelectItem object but dont know, why?
When I am using hard coded selecItem tag it is not giving any errors only while using selectItems...I searched a lot lot but never able to find out a satisfactory reason nor solution...I will provide my code..jst have a look at it..

My UIForm code
<ga:responseActions>
<id:listProjectLeaders target="#{plList}"/>
</ga:responseActions>
<h:selectOneMenu value="#{var['pl']}">
<f:selectItems value="#{plList}" />
</h:selectOneListbox>

I am getting data from database in dropdown list but not able to select..

My getMethod
public List<SelectItem> getProjectLeaders() {
List<SelectItem> projectLeaders = new ArrayList<SelectItem>();
SelectItem option = null;
String count = null;
Query query = session.createQuery(
"select usr.fullName from org.jbpm.identity.User as usr " +
"where usr.id in(select mbr.user.id from org.jbpm.identity.Membership as mbr " +
"where mbr.role = 'Project Leader')"
);
List lead = query.list();

System.out.println("================================");
System.out.println("Size of List = "+lead.size());
System.out.println("================================");

for(int i=0; i<lead.size(); i++)
{
pl = lead.get(i).toString();
count =String.valueOf(i);
option = new SelectItem(pl, pl);
projectLeaders.add(option);
}
System.out.println("================================");
System.out.println("================================");
System.out.println("PROJECTlEADERS = "+projectLeaders);
System.out.println("================================");
System.out.println("================================");

return projectLeaders;
}

Now what error, I am getting after clicking on submit button

<h:selectOneMenu value="#{var['pl']}">
<f:selectItems value="#{plList}" />
</h:selectOneListbox>

The closing tag looks incorrect.

Also the select item value should be BB.Arraylist (containing SelectItems objects).

I have not worked with GA so I might be wrong.
