I re-built the Branch_5_x with the 2.2.0-SNAPSHOT and then it worked as expected and the undeploy error is done. Looks good :) Would it be alright to update the Branch_5_x to use this version of the deployers you think? Would make it easier for others to try this out and provide us feedback. Thanks for you quick response on this! /Daniel View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4228637#...
