Binding attribute in #ViewScoped causes remote EJB to throw java.io.NotSerializableException - jsf

Question

When I send an object of class which doesn't implement Serializable to remote EJB it handles it, but things change when one field of this class is a programmatic UIComponent used in binding attribute from a #ViewScoped backing bean. In second case java.io.NotSerializableException is thrown.
Form
<h:form>
<p:panel binding="#{bean.notSerializableObj.pfPanel}"/>
<h:inputText value="#{bean.notSerializableObj.someString}" />
<p:commandButton value="GO" action="#{bean.sendToEjb}"/>
</h:form>
Backing bean
#Named(value = "bean")
#ViewScoped
public class Bean implements Serializable {
#EJB
private RemoteEjbService service;
private NotSerializableClass notSerializableObj;
public NotSerializableClass getNotSerializableObj() {
return notSerializableObj;
}
public void setNotSerializableObj(NotSerializableClass notSerializableObj) {
this.notSerializableObj = notSerializableObj;
}
#PostConstruct
private void init() {
Panel p = new Panel();
System.out.println("INIT Panel: " + p);
notSerializableObj = new NotSerializableClass("myObject", p);
}
public void sendToEjb() {
System.out.println("Sending to EJB");
trySending();
System.out.println("Second try with new object");
Panel p = new Panel();
notSerializableObj.setPfPanel(p);
trySending();
}
private void trySending() {
try {
System.out.println("Panel: " + notSerializableObj.getPfPanel());
service.notSerializableTest(notSerializableObj);
System.out.println("Sent correctly");
} catch (Exception e) {
System.out.println("Exception: " + e);
}
}
}
NotSerializableClass
public class NotSerializableClass {
private String someString;
private Panel pfPanel; // PrimeFaces panel not implementing Serializable
public NotSerializableClass(String someString, Panel pfPanel) {
this.someString = someString;
this.pfPanel = pfPanel;
}
//getters setters
}
Results
Info: INIT Panel: org.primefaces.component.panel.Panel#9f68a9
Info: Sending to EJB
Info: Panel: org.primefaces.component.panel.Panel#9f68a9
Info: Exception: javax.ejb.EJBException: java.rmi.MarshalException: CORBA BAD_PARAM 1398079494 Maybe; nested exception is:
java.io.NotSerializableException: WARNING: 00100006: Class test.NotSerializableClass is not Serializable
Info: Second try with new object
Info: Panel: org.primefaces.component.panel.Panel#e59fd7
Info: Sent correctly
On the first try exception is thrown, on the second try object was successfully send despite not implementing Serializable. When I removed binding attribute there wasn't any exception thrown in the first trySending().
There is no difference if I set javax.faces.STATE_SAVING_METHOD to server or client. But it works if bean is #RequestScoped or #SessionScoped or remote interface is replaced with local one.
The question is: What changes in object when it is connected to binding attribute because somehow EJB can't handle it afterwards?
Panel wasn't serialized after creation because hashcode in #PostConstruct and submitting method is the same.
