[jboss-user] [JBoss jBPM] - Re: Action not executing in timer

[kukeltje]

I don't think you will have any luck with your Jira issue. Let me explain a little more (this can be read in other articles as well, even the jBPM docs I think)

Normally the client only has 'control' for a very small amount of time. A second is a lot already. Timers that need to go off within a second are mostly useless. Remember, this is mainly workflow!!! so clashes occur rarely

If a transition is taken and after that something goes wrong, the best thing to do is to go back to the last wait-state. That is the situation where external action was needed. That external action can be repeated (e.g. task not ended, user has to do it again) This is easiest done with a transaction roll-back in the database. Committing on each node boundary or even within nodes (creation of timers) would make this impossible to do and result in a lot more complicated system.

If you want to have a STP system with (probably) persistency on nodes etc... you can have a look at the PVM and simply develop your own language and behaviour on top of that. Might also be that an 'stp' language is developed, though I'm not sure.
