Hi, thx for the guide, its very helpfull for newbies like me, but i have a little problem with it;( on figure 21 you say "Double-click gpd.xml to open it up in the viewer". That doesnt work for me, it open only the file with the xml-editor? I try to open it with "open with -> Other -> jBPM Graphical Process Designer", but then i get an error. java.lang.ClassCastException: org.jbpm.gd.jpdl.model.ProcessDefinition cannot be cast to org.jbpm.gd.common.model.GenericElement When i double-click the processdefinition.xml all work fine ... so i dont know if its only a newbie problem or if the tutorial isnt right there? Maybe i am the only one with this problem? ;) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4094066#...
