Drop zone inside an other dropzone

Hi

When a dragzone2 is inside a dragzone1 : no problem.
When a dropzone2 is inside a dropzone1 : only dropzone1 is seen by richfaces.

Here is a simple code :


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"

 xmlns:a="http://richfaces.org/a4j"
 xmlns:c="http://java.sun.com/jstl/core"
 xmlns:rich="http://richfaces.org/rich">

<body>
<f:view>

 <rich:panel>
 <rich:dragIndicator id="indicator" />
 <a:form id="form">
 <rich:panel>
 <f:facet name="header">
 <h:outputText value="dragzone1" />
 </f:facet>
 <rich:dragSupport dragIndicator=":indicator" dragType="zone"
 dragValue="dragzone1">
 <rich:dndParam name="label" value="dragzone1" />
 </rich:dragSupport>
 <rich:panel>
 <f:facet name="header">
 <h:outputText value="dragzone2" />
 </f:facet>
 <rich:dragSupport dragIndicator=":indicator" dragType="zone"
 dragValue="dragzone2">
 <rich:dndParam name="label" value="dragzone2" />
 </rich:dragSupport>
 <h:outputText value="dragzone2" />
 </rich:panel>
 <h:outputText value="dragzone1" />
 </rich:panel>
 <rich:panel>
 <f:facet name="header">
 <h:outputText value="dropzone1" />
 </f:facet>
 <rich:dropSupport acceptedTypes="zone" dropValue="dropzone1"
 dropListener="#{test.processDrop}" />
 <rich:panel>
 <f:facet name="header">
 <h:outputText value="dropzone2" />
 </f:facet>
 <rich:dropSupport acceptedTypes="zone" dropValue="dropzone2"
 dropListener="#{test.processDrop}" />
 <h:outputText value="dropzone2" />
 </rich:panel>
 <h:outputText value="dropzone1" />
 </rich:panel>
 </a:form>
 </rich:panel>

</f:view>

</body>
</html>

And backbean :

public void processDrop(DropEvent dropEvent){
 log.info("processDrop on : "+this);
 log.info("Drag value : "+dropEvent.getDragValue());
 log.info("Drop value : "+dropEvent.getDropValue());
 }

This example shows dropzone2 is not visible.
Dragzone2 is visble.

My question is :
Is it difficult to change this feature ?

Thanks in advance.
