Leonardo Uribe commented on MYFACES-2395:
-----------------------------------------
Note the param:
org.jboss.jbossfaces.WAR_BUNDLES_JSF_IMPL
just prevent init RI but does not remove from the classpath (but that's enought
for most applications).
> Cant' run two JSF portlets on the same portal page

> This exception allways happen with the second portlet on the page, whichever
> it is. I tried with many portlets, but so you can reproduce the problem I'm
> attaching the wars for two very simple portlets.
> I'm filling this under MyFaces Core instead of Portlet Bridge because the
> same applications, if deployed to use Mojarra (included in JBoss AS 4.2) and
> the same portelt bridge jars, work fine.
