[jboss-dev-forums] [Design of JBoss jBPM] - Re: execution transitions, data flow and other associations

[tom.baeyens@jboss.com]

brittm: i'm not yet convinced about the shared processes as a general concept to pursue in jpdl.  the implications are far reaching and i'm not yet sure this is a common use case.

one thing that might help you already a little bit is that in jbpm 4 we will be componentizing the node implementations.  so that you can build complete node packages, including jPDL-parsing, hibernate persistence, actionHandler based implementation, designer form, icon, ...  That way it will become more feasible to develop your own custom node and really integrate it into the current runtime and toolset.

maybe the shared subprocesses could become part of jbpm as a kind of advanced or add-on node package, not part of the default configuration.


About links: i think they are something different.  Each link is a named boolean that connects two concurrent paths of execution.  Then, the target activity has an boolean expression as a function of the arriving links.  The activity will only be executed if the link expression resolves to true.  But Alex will know better.
