Maurice, I think you're looking for a level of metadata that's not at all present in jBPM. A more general case of what you're looking for is a reusable node template, which has defined inputs and outputs that are bound in a given process definition to specific values (sometimes process variables, sometimes other things). Extending this, you might consider "stencils" (a la Visio) that are collections of such node templates that apply to a specific application domain. This is all blue sky - maybe Ronald will say whether there's any work being considered in this direction. You need to think carefully about whether a subprocess will do what you need. The fact that it has a separate process identity may complicate your life, depending on how you need to do things like externally monitor the process state. If you want to investigate the state of the outer process down to the states within the inner process, there's extra work involved. -Ed Staub View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4004018#...
