We just released JBoss Portlet Bridge Beta3 along with some good supporting documentation and  example projects.
See the documentation for full details
.
For those that want to jump right in, you can run the following archetype and have it deployed on JBoss AS + Portal in minutes:
mvn archetype:generate -DarchetypeGroupId=org.jboss.portletbridge.archetypes -DarchetypeArtifactId=1.2-basic -DarchetypeVersion=1.0.0.B3 -DgroupId=org.whatever.project -DartifactId=myprojectname -DarchetypeRepository=http://repository.jboss.org/maven2/ -Dversion=1.0.0.B3
mvn install cargo:start -Premote-portal -Dpc20
mvn cargo:deploy -Premote-portal -Dpc20

The majority of the code written for this release is internal to the
portlet bridge project (refactoring, 301 spec updates and enhancements,
bug fixes...). The next release (Beta 4 - early Sept) will be huge for
the portlet bridge for the following reasons:

• The EG is currently discussing a lot of significant
  clarifications and improvements. For example, working with the JSF 2.0
  EG to allow certain needs and working on Portlet 2.0 areas of the spec.
  
• There is currently a lot of discussion about navigation
  between portlet modes. Once this is nailed down in the spec, we will
  implement it.
  
• The Portlet 1.0 version should be getting close to public review.

Other
than the spec related reasons for release schedule, we must work in
unison with the latest Seam and RichFaces relases, make sure that we
squash any bugs concerning the 3 integration points, handle
features/improvements/refactorings, and try to test and give feedback
to the 301 EG. And, of course we can't forget about JBoss Portal 2.7+!
There are soo many cool things going on right now within the JBoss
Portal project, I would like to tell you about all of them but then
this post wouldn't be about JBPB anymore. Just stay tuned to this
blog...
With that said, here are a few tips for JSF portlet developers that
concern this release:

• NamespacingIn situations where you need to
  use the id of an element in your JSF/xhtml markup, you would normally
  see something like 'form1:myBtn' in the rendered markup. But now with
  the bridge namespacing you will see something similar to: jbpns_2fdefault_2fNews_2fStories_2fStoryTemplateWindow12snpbj:_viewRoot:form1:myBtn
  To overcome this, you can use the following expression in your Facelets page to prepend the namespace to your javascript code:
  document.getElementById('#{facesContext.externalContext.response.namespace}the_rest_of_JSF_ID
  since this uses the portletResponse, once you try to view this page on
  the servlet application side, you will get an exception. To avoid this,
  you need to check for the type of response in your backing bean and
  assign a new "safe" namespace variable for the UI.
  
• Excluding Attributes from the Bridge Request ScopeWhen
  your application uses request attributes on a per request basis and you
  do not want that particular attribute to be managed in the extended
  bridge request scope, you must use the following configuration in your
  faces-config.xml. Below you will see that any attribute namespaced as
  foo.bar or any attribute beginning with foo.baz(wildcard) will be
  excluded from the bridge request scope and only be used per that
  application's request.
       
           
               foo.bar
               foo.baz.*
