"support-public-render-paramter" or "coordination feature"

hello everybody,

iam using jboss portal 2.7.2 with jsf 1.1.14, richfaces 3.1.1 and of course the portletbridge 1.0.0.CR1.

Now i have to send Integer Parameters from Portlet A to Portlet B.
Therefor i found an example which says,

1. in the protlet.xml

<init-param>
 <name>com.sun.faces.portlet.SAVE_REQUEST_SCOPE</name>
 <value>true</value>
</init-param>

2. also in portlet.xml

<portlet-app>
 <portlet>
 ...........
 <supported-public-render-parameter>helloForm:userNo</supported-public-render-parameter>
 </portlet>
 <public-render-parameter>
 <identifier>helloForm:userNo</identifier>
 <qname xmlns:x="http://www.sun.com/params">x:userNumber</qname>
 </public-render-parameter>
</portlet-app>

3. in the jsf file of the sending portlet (...xhtml)

<f:view>
 <h:form id="helloForm">
 .............
 <h:inputText id="userNo" value="#{UserNumberBean.userNumber}"
 validator="#{UserNumberBean.validate}"/>
 .................
 </h:form>
</f:view>

4. in the jsf file (...xhtml)

FacesContext context = FacesContext.getCurrentInstance();
PortletRequest request = (PortletRequest)context.getExternalContext().getRequest();
return request.getParameter("helloForm:userNo");

to get the public paramter.

i become no error, but also not the parameter.

the question is, do someone knows how to send a parameter from portlet A to B?

Thx for reading my question!

I have to correct my statements:

3. This point is in the xhtml file of the sending portlet. It use a java file which stores this value.

4. This point is in the java file of the receiving portlet. here i should receive the parameter from the request. afterward it will be picked up from the xhtml file.
