The documentation is as follows: anonymous wrote : We don't lock you into any one JavaServer Faces implementation. You can always select the one which is necessary for you while creating a new JSF project, adding JSF capability to any existing Eclipse project or importing existing JSF projects as well. Emphasis mine. http://www.redhat.com/docs/en-US/JBoss_Developer_Studio/en/jsf_tools_ref_... So how can I add different versions of MyFaces so I see them listed as choices in the "special wizard" that prompts to specify a proper JSF environment? I want to add MyFaces 1.2.6 and have it set up without manually adding the .jars. Thanks View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4238852#...
