I download the source and I am trying to modify something, like a hello world. Fox example, I change in the constructor of the class TaskFormGenerationDialog, the line this.title = "Generate Task Form" for this.title = "Generate Task Form Test"; I run the "All" target and copy the generate files in Users/user/jbpm/repository/jbpm/designer/jpdl/3.0.13.1/jbpm-jpdl-designer/eclipse for my eclipse folder. But I started the eclipse and the changes are not avaiable. The process to implement jpdl is this ? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4080689#...
