s:convertEntity throws NullPointerException
Hi All,
I would like to use s:convertEntity in my h:selectOneListBox, but when I'm calling my page it returns with NullPointerException.
This is my components.xml:

@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="sources_sourceid_seq")

public void setSource(String source) {

}And this is my action bean:
@Startup
@Stateful
@Name("hireAction")
@Scope(ScopeType.SESSION)
public class HireActionImpl implements HireAction {
@In
private Session drsession;
@DataModel
private List<Source> sourceList;
@DataModelSelection(value="sourceList")
@Out(required=false, value="selectedSource")
private Source selectedSource;
@Create
public void init(){
this.sourceList=new ArrayList<Source>();
this.selectedSource=new Source();
}
//GETTERS & SETTERS
}This is the part of the xhtml page where I'm using s:convertEntity:
<h:selectOneListbox id="sourceListBox" value="#{selectedSource}" size="1">
<s:selectItems id="sourceItems" value="#{sourceList}" var="sss" label="#{sss.source}"/>
<s:convertEntity/>
</h:selectOneListbox>When I'm calling this page I'm receiving this error message:

If I'm removing the s:convertEntity tag it's working fine (but of course it not converts my Source entity).
I'm using JBoss 4.2.3 and Seam 2.1 GA (I tested it with Seam 2.1 SP1 and Seam 2.0.2, but the result was the same).
Is there anyone who has anu idea about this issue?
Thanks,
Tamas
