[jboss-user] [jBPM] - Re: Exception Handler support in jBPM 4.4

Michael Wohlfart [http://community.jboss.org/people/mwohlf] created the discussion "Re: Exception Handler support in jBPM 4.4" To view the discussion, visit: http://community.jboss.org/message/570118#570118 -------------------------------------------------------------- What I had in mind was something like a NPE because one of your process variables is not initialized, for example a programming error in your form validation. I don't think low level exceptions like this should be handled in a higher level context like the Process Engine, you could probably initialize a transition into an "error" state but this would violate the "Crash, Don't Trash" principle. Having said that, I also think it probably makes sense in some cases to have an exception handling in your process definition. As far as I know this is implemented in jBPM3, see:  http://docs.jboss.org/jbpm/v3/userguide/jpdl.html#exceptionhandler.element http://docs.jboss.org/jbpm/v3/userguide/jpdl.html#exceptionhandler.element, unfortunately jBoss stopped development on jBPM4 before this was implemented in jBPM4. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/570118#570118] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
