Why do I can alway get label in getAsObject() in Primefaces? - jsf

Question

I do not why although I verify everything which is right. Anyone know?
I tried to debug:
- getAsString() return ID (that's right)
- when I submitted - getAsObject() always throw exception because the label values was always passed instead of ID values.
My code as below:
my xhtml file:
<div class="ui-grid-row" style="margin-top: 5px; margin-bottom: 5px;">
<div class="ui-grid-col-2 pdt4">
<p:outputLabel for="txtApprovalScheduler"
value="#{lang['workforce.category.parttimeManagement.approved.scheduler']}"/>
</div>
<div class="ui-grid-col-2">
<p:selectOneMenu value="#{parttimeController.selectedAgentDTO}"
id="txtApprovalScheduler"
filterMatchMode="contains" editable="true"
style="width: 86%;"
required="true"
requiredMessage="#{lang['workforce.category.parttimeManagement.approved.scheduler.missing']}">
<f:converter converterId="agentConverter"/>
<f:selectItem itemValue="" itemLabel="#{lang['wf.common.choose']}"/>
<f:selectItems value="#{parttimeController.agentDTOs}" var="agentItem1"
itemLabel="#{agentItem1.userName}"
itemValue="#{agentItem1}"/>
</p:selectOneMenu>
</div>
<div class="ui-grid-col-2 pdt4">
<p:outputLabel for="txtApprovalRegister"
value="#{lang['workforce.category.parttimeManagement.approved.register']}"/>
</div>
<div class="ui-grid-col-2">
<p:selectOneMenu value="#{parttimeController.selectedAgentDTOForRegister}"
id="txtApprovalRegister" editable="true"
filterMatchMode="contains" style="width: 86%; font-size: 12px !important;"
required="true"
requiredMessage="#{lang['workforce.category.parttimeManagement.approved.register.missing']}">
<f:converter converterId="agentConverter"/>
<f:selectItem itemValue="" itemLabel="#{lang['wf.common.choose']}"/>
<f:selectItems value="#{parttimeController.agentDTOs}" var="item1"
itemLabel="#{item1.userName}"
itemValue="#{item1}"/>
</p:selectOneMenu>
</div>
</div>
My Converter:
#FacesConverter(forClass = AgentDTO.class,value = "agentConverter")
public class AgentConverter implements Converter {
public static List<AgentDTO> listAgentDTOs;
#Override
public Object getAsObject(FacesContext facesContext, UIComponent uiComponent, String agentId) {
if (agentId.trim().equals("")) {
return null;
} else {
try {
Long number = Long.parseLong(agentId);
for (AgentDTO a : listAgentDTOs) {
if (a.getAgentId() == number) {
return a;
}
}
} catch (NumberFormatException exception) {
throw new ConverterException(new FacesMessage(FacesMessage.SEVERITY_ERROR, "Conversion Error", "Not a valid data"));
}
}
return null;
}
#Override
public String getAsString(FacesContext facesContext, UIComponent uiComponent, Object value) {
if (value == null || value.equals("") || "-1".equals(value)) {
return "";
} else {
String result = String.valueOf(((AgentDTO) value).getAgentId());
return result;
}
}
}
My bean:
#Component
#Scope("view")
#ManagedBean(name = "parttimeController")
public class ParttimeController extends BaseController implements Serializable {
private AgentDTO selectedAgentDTO;
private AgentDTO selectedAgentDTOForRegister;
private List<AgentDTO> agentDTOs;
.... getter/setter and initiallize AgentCenvert.listAgentDTOs
My class:
public class AgentDTO{
private Long agentId;
private String userName;
....getter/setter
}

I found out the reason - I only remove editable attribute in selectOneMenu. So getAsObject() will pass a value instead of a label
