Hi,
i have already postet this issue to seam forum i'am not sure if it is a seam or RF issue.
I can not get work simple thing that works under pure richfaces and don't want to work together with seam. The simple commandLink just works (new browser will be opened and the output goes to it) with simple richfaces web application. As i put seam to the application, only put the jars to lib dir and configure listener a.s.o. nothing special (so all requests go throught seam) the output goes to the "old" browser page, no new page is opened.
<a4j:commandLink action="#{bean.showReport}" value="download" target="_blank"> </a4j:commandLink>
