Tihomir,
Your advice to upgrade the designer (I actually upgraded to .055) solved my deployment issues documented here (http://community.jboss.org/thread/160213?start=30&tstart=0) and here (http://salaboy.wordpress.com/2011/03/09/jbpm5-community-training-%E2%80%93-module-5-domain-specific-processes/). Thanks! I know I'm probably doing something wrong, but I've been a bit surprised at how hard it is to deploy a process to the server. Thanks again!
Ronnie
