primefaces autocomplete event itemSelect listener value null in ManagedBean

问题

I am using Primefaces 3.4.2 Autocomplete.

In ManagedBean when I select a row as I type characters in autocomplete, I am not able to get the value in method handleSelect(SelectEvent event) {

What could be the reason for this? Ideally I would like to fill or populate other columns in jsf page when I select a row from autocomplete values.

JSF code for autocomplete

<p:autoComplete value="#{empMB.selectedEmployee}"
                            id="basicPojo" minQueryLength="3" 
                            completeMethod="#{myMB.complete}" var="p"
                            itemLabel="#{p.empName}" 
                             converter="#{employeeNameConverter}"
                            forceSelection="true" >                           
                            <p:ajax event="itemSelect" 
                            listener="#{myMB.handleSelect}" /> 

ManagedBean method

public void handleSelect(SelectEvent event) {
String value = (String) event.getObject();
System.out.println("selected "+value);

The reason is you didn't provide itemValue attribute in p:autoComplete component.
