Drag and Drop Exception and problem

[vendetta]

Hi at all, I use richFaces 3.1.4 and I try to develop an easy dnd example but it does not work well.

JSP code :

...

<a4j:form ajaxSubmit="true">
 <rich:panel style=" border : 0;" rendered="true">
 <rich:dragIndicator id="indicator" />

 <a4j:outputPanel
 style="width:100px;border:1px solid gray;padding:2px"
 layout="block">

 <rich:dragSupport dragType="text" dragValue="#{EventBean.drag}"
 dragIndicator="indicator" />
 <h:outputText value="#{EventBean.drag}" />

 </a4j:outputPanel>

 <rich:panel id="drop">
 <rich:dropSupport acceptedTypes="text"
 dropListener="#{EventBean.processDrop}" reRender="drop, drag" />
 <h:outputText value="#{EventBean.drop}" />
 </rich:panel>

 </rich:panel>

</a4j:form>

...

EventBean :

package it.iwbank.opv.client.managedbean;

import it.iwbank.lib.refactoring.managedbean.ManagedBean;

import org.richfaces.component.Dropzone;
import org.richfaces.event.DropEvent;
import org.richfaces.event.DropListener;

@SuppressWarnings("serial")
public class EventBean extends AbstractManagedBean implements DropListener, ManagedBean {

 private String drag;
 private String drop;

 public EventBean() {
 this.drag = "Drag";
 this.drop = null;
 }

 public void processDrop(DropEvent dropEvent) {
 System.out.println("+-+ EventBean.processDrop");
 Dropzone dropzone = (Dropzone) dropEvent.getComponent();
 this.moveSwitchString(dropEvent.getDragValue(), dropzone.getDropValue());

 }

 public void moveSwitchString(Object fm, Object family) {

 System.out.println("+-+ DndBean.moveFramework");

 if ("text".equalsIgnoreCase((String) family)) {
 this.drag = "";
 this.drop = "Drop";
 }
 }

 public String getDrag() {
 return drag;
 }

 public String getDrop() {
 return drop;
 }
}

When I move the dragSupport into dropSupport the Framwork arise to me thi exception
