To view the discussion, visit: http://community.jboss.org/message/557465#557465 -------------------------------------------------------------- Hi HuiSheng, thanks for your answer. Yes I know that, but I don't undestand why SubProcessBinding class looks for the org/jbpm/pvm/internal/model/Activity class instead the new class. I only modified the new SubProcessActivity.java and updated  SubProcessActivity.class and SubProcessBinding.class in jbpm.jar of 4.4 release. I will try to update only SubProcessActivity.class... -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/557465#557465] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
