IMO we need to make sure that conceptual things (bare bone) that relate to the API sand CTS have foremost priority when we meet. At least we should try to draw a line between implementation detail and concepts and leave the details to the person implementing it. Something else: If you come up with things that need to be considered, discussed or reviewed then raise an issue (JIRA) right away. Otherwise it get's easily lost.

[Design of JBoss jBPM] - Re: Cancelling a task fires task-end event

Ronald, If you are using this construction: | if (this.isCancelled) { | task.fireEvent(Event.EVENTTYPE_TASK_CANCEL, executionContext); | } else { | task.fireEvent(Event.EVENTTYPE_TASK_END, executionContext); | } | Then you are missing the TASK_END event if the task is cancelled. People for who see 'finishing a task ' (ie. cancelling or completing) as the end of a task (which is conceptually also correct) and now simply use an event handler for the TASK_END event are obliged to use 2 event handlers now. So it comes down to a matter of conceptual view: - Ending a task == the task is finished (removed by cancelling or successfully completed) - Ending a task == completing the task successfully, BUT cancelling means here that the task did not end but simply dissapeared for some reason. I have implemented both use cases in the past, so this is not some academic example. What we need here is a solid and clear definition ... anonymous wrote : | Otoh, I've not heard people complaining about taskmanagement regarding the 'states' of task management do you guys? Questions were more about declaring vars, typing them, giving default values etc | That's true ... but I did have a use case in which the states of a task were THE most import thing: cancelled, suspended, ended, assigned but not taken, working on it, etc. all those states were possible for a task. So you can imagine I would have been very happy at that moment if I had some more options ... we had to juggle a bit with task variables to get it all done.

Could be, but that makes it more difficult to implement. You can get that functionality by declaring 2 event-handlers as mentioned above.... I would not make it overly complicate. But if kind of hierarchical events are introduced, that would be fine to. In that case we agree and is it less complex/difficult than we thought.

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Adding Ordering Group Features in JBM 1.4

by timfox

I have updated the docs and readme so they reference the correct jar versions and release numbers. I have also released the project in JIRA What remains to be done before releasing: 1) Make sure all the examples run through 2) Update remoting config in the docs with the version in the release Other things to do (maybe done already?) 1) Make sure eap 4.3 service binding manager config is updated with our new config. 2) Make sure any JBM config files in EAP 4.3 have been updated with our new config.

I deleted the tag to prevent anyone taking it prematurely. Next time, I want to see a review process before tagging. This same mistake of not updating readme and documentation seems to happen regularly every single time.. :( View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4180710#4180710 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4180710

Please don't use that branch. The release will need to be re-tagged since readme and docs weren't updated properly. The release notes still refer to 1.4.1.beta1 (!) and reference the incorrect project in JIRA, as does the documentation.
