I read all documentation about RichFaces, search in forums etc, but i haven't found official instruction about using RichFaces in portal environment (not only in JBoss Portal).
I've found only examples and forum threads with sample code with a lot of various configurations.
And what bridge library i have to use - ajax4jsf-portlet, richfaces-portlet (api&impl?) or portlet (i found that in jboss maven repo)?
Where can i get it as binary? (as i understand only as source or in maven-repo)
I think it's necessary to create wiki or guide with basic RichFaces configuration for portal environment and may be some tips&triks about configuration in specific portals.
you can get a Richfaces portlet from here: http://anonsvn.jboss.org/repos/portletswap/portlets/src/framework/RichFacesPortlet
By looking at the source code you should be able to get a picture of what's do be done to create JSF portlets based on Richfaces.
