Hmm Thats weird, we also use 3.2.3 here on a jboss server 4.2GA release and a mysql database 5.x No idea why the cascades dont work then on our installations Regards, Leo mputz wrote : anonymous wrote : The case i have is that Comment objects are attached to tokens in the process instance. | | I just tested GraphSession.deleteProcessInstance on a process with related comments, and they were deleted just fine.

Hey, I just wrote a handler to get rid of all the process instance data including the cascades. The actual delete is kinda tricky in a sense that since all collections and object properties are lazily initialized it requieres you to load them up in a custom command object to get the actual data, then run through them, clear them and only then will a delete on process instance throught the jbpmContext work correctly with all cascades.

If I were to perform a hibernate delete on the process instance would it cascade and delete everything associated with the process instance?

That wont work since you will have a non complete processinstance at your hands caused by all lazy loading on the process instance...

Leo, the GraphSession.deleteProcessInstance method *should* handle all references correctly, and should thus get rid of all data related to a process instance. If it does not, it would be great if you could provide more info about what is missed out, so that this can be fixed.

Sure,
I dont claim this to be perfect but hey it works, so here is the code for the
handler:
| public class VerwijderProcessInstanceHandler extends JbpmHandlerProxy{
| private static final long serialVersionUID = -6125309218094541298L;
| /** Logger available to subclasses */
| protected final Log logger = LogFactory.getLog(getClass());
|
| @SuppressWarnings(unchecked)
| @Override
| public void execute(ExecutionContext executionContext) throws Exception {
| try {
| logger.debug(executing VerwijderProcessInstanceHandler...);
| ProcessInstance pi = executionContext.getProcessInstance();
| logger.debug(ProcessInstance is null? + (pi==null));
| ListToken allTokens = pi.findAllTokens();
| logger.debug(allTokens of processInstance: + allTokens.size());
|
| //clear taskinstances from comments
|CollectionTaskInstance taskInstances =
pi.getTaskMgmtInstance().getTaskInstances();
| for(TaskInstance ti : taskInstances){
| ti.getComments().clear();
| executionContext.getJbpmContext().save(ti);
| }
|
| //clear tokens from comments..
| if(allTokens.size() 0){
| for(Token t : allTokens){
| //get all comments per token...
| if(!t.getComments().isEmpty()){
| logger.debug(cleared comments before deleting? +
t.getComments().isEmpty());
|
| for(Object o : t.getComments()){
| Comment c = (Comment)o;
| c.setTaskInstance(null);
| }
|
| //clearing comments on taskinsantce manually... pfff
| t.getComments().clear();
|}
|
| executionContext.getJbpmContext().save(t);
| logger.debug(t.getComments().size(): + t.getComments().size());
| }
| }
|
| //saving without comments and taskinstances within comments...
| executionContext.getJbpmContext().save(pi);
|
|
executionContext.getJbpmContext().getGraphSession().deleteProcessInstance(pi,
true, true);
| } catch (Exception e){
| //Exception upon deleting processinstance..
| e.printStackTrace();
| logger.error(e.getMessage());
|}
| }
| }
|
Basically I have this handler configured in a Spring application context and
then use the spring-jbpm integrationproxy. So I call this handler from within
my jBPM process on the action like so:
| end-state name=end-bevestigRelatieVerzoek
| event type=node-enter
| action name=verwijderProcessInstanceAction
class='org.springmodules.workflow.jbpm31.JbpmHandlerProxy' config-type=bean
| targetBeanVerwijderProcessInstanceHandler/targetBean
|/action
| /event
| /end-state
|
Allthough I strongly agree with you that I expect the jBPM (engine) to cleant
up all process data after a processinstance finishes and I consider it to be a
bug that it doesnt ! Coming from working for years with commercial workflow
engine products the default behaviour I have allways encountered is to purge
all data from the BPM database upon completion. This ensures a lean and mean
processing database necesary for speedy processing with large numbers of
processinstances or cases. If you then need historical data you as a developer
store that in a seperate database
But maybe some of the core jBPM folks in here could comment on this ?
Greetings and now off to my weekend,
Leo

[jboss-user] [JBoss jBPM] - Re: Terminated or deleted process instance?
hey, Well as you can see from my handler code above that is the only way I could get GraphSession.deleteProcessInstance to delete the ProcessInstance and to have the cascades work correctly. The case i have is that Comment objects are attached to tokens in the process instance. Basically I had to clean out all references to the Comments everwhere manually as you can see from my code. Without this 'cleanup' code I get exceptions back from hibernate basically telling me there are references on Comment instances left so the delete fails.

[jboss-user] [JBoss jBPM] - Re: Terminated or deleted process instance?
Aha, ok. So, the process instance is not deleted after it has been terminated? Can I restart it, if I know its ID?

[jboss-user] [JBoss jBPM] - Re: Terminated or deleted process instance?
look at my last remarks about 'restarting' and yes you need something like the id. Restarting from the beginning is *not* automatically done, unless you e.g. move the root token to the start node, but behaviour would probably be strange in some cases since there are already process variables with values View the original post : http://www.jboss.com/index.html?module=bbop=viewtopicp=4170521#4170521 Reply to the post : http://www.jboss.com/index.html?module=bbop=postingmode=replyp=4170521 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

Depends... you can make the end date of the process null, then it is 'running' again, but the node it is in will still be the end node...
