[JBoss Seam] - Re: Using Seam for porlet communication
by jarkko＠jab.fi
This allows intra/inter portlet to portlet communication inside Seam. Basically everything that goes to Session scope is also put to both PORTLET_SCOPE(portlet private, only the portlet putting has access to it) and APPLICATION_SCOPE (portal wide, every portlet inside portal sees it). A more elegant/resource wise solution might be better, but it is not actually trivial without adding new configuration options.
