I'm using primefaces 4.0.7 .I used selectonemenu,this menu showed the variables however value was null in Bean.Is there any configuration can i do?
Here is part of xhtml code;
<h:outputText value="#{etiketler.kullaniciTipi} : " />
<p:selectOneMenu id="kullaniciTipi" style="width:200px" value="#{kullaniciIslemleriBean.userRole}" >
<f:selectItems value="#{enumBean.kullaniciTipiValues}" var="kullaniciTipi"
itemLabel="#{kullaniciTipi.name}" itemValue="#{kullaniciTipi}" />
</p:selectOneMenu>
here is part of kullaniciIslemleriBean code;
private EnumBase.KullaniciTipi userRole;
public void Kaydet() {
if (userRole == null) {
System.out.println("null value");
return;
}
...
}
public EnumBase.KullaniciTipi getUserRole() {
return userRole;
}
public void setUserRole(EnumBase.KullaniciTipi userRole) {
this.userRole = userRole;
}

Answer 1

Try storing it as String, it will work fine. If you want to store it
as Enum then try converter
<h:outputText value="#{etiketler.kullaniciTipi} : " />
<p:selectOneMenu id="kullaniciTipi" style="width:200px" value="#{kullaniciIslemleriBean.userRole}" >
<f:selectItems value="#{enumBean.kullaniciTipiValues}" var="kullaniciTipi"
itemLabel="#{kullaniciTipi.name}" itemValue="#{kullaniciTipi.name}" />
</p:selectOneMenu>
private String userRole;
public void Kaydet() {
if (userRole == null) {
System.out.println("null value");
return;
}
...
}
public String getUserRole() {
return userRole;
}
public void setUserRole(String userRole) {
this.userRole = userRole;
}
