We never had this problem with the original installation or when we upgraded the designer from  1.0.0.052-jboss to 1.0.0.055-jboss Have we missed any step or configuration during the upgrade process? Thank you very much in advance. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/640372#640372] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
