URL rewrite with @RequestParameter

[hitcurst]

Hello, i'm starting with Jboss Seam 2.2.0 and i'm get one error with URL Rewrite.
I have this code:

topicList.xhtml

<rich:panel>
     <a4j:form>
          <a4j:commandButton value="#{msg['topic.newTopic']}"
               action="#{commonTopicManager.createNew}">
               <f:param value="#{commonTopicManager.forum.idForum}" name="idForum" />
          </a4j:commandButton>
     </a4j:form>
</rich:panel>

topicList.page.xml

<navigation from-action="#{commonTopicManager.createNew}">
     <redirect view-id="/service/common/topic/topicEdit.xhtml">
          <param name="idForum" value="#{commonTopicManager.forum.idForum}" />
     </redirect>
</navigation>

Then, in the new page:

topicEdit.page.xml

<rewrite pattern="/TopicEdit/{idForum}"/>
<param name="idForum" value="#{param.idForum}" />

But this don't work. this not work too:

<rewrite pattern="/TopicEdit/{idForum}"/>
<param name="idForum" value="#{commonTopicManager.forum.idForum}" />

Anyone have one solution ?
