Well,
If the workaround to get rid of the exceptions happening is to lower the log
level ie you dont see them anymore that only gets rid of the log entry.
If you use transactional service from within your timers ie handlers with
services that use transactions they will fail on the transactions

Well,
Here is one usecase we are currently facing. We have lots and lots of timers
spread around over many processinstances. The timers are pretty much only
expring once every few months so are long outstanding timers.
We started of with EJB timers untill recently i discovered exactly this, that

True,
I understand the current implementation but in my view functionally they
shouldnt be different things. I feel you need to be able to have them to

to have the process instance be able to do two optional things:

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

processing database necesary for speedy processing with large numbers of
processinstances or cases. If you then need historical data you as a developer

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

Hey,
Yeah I am aware of this function call, question remains though where to call
it.. Ideally I would like the process at the end to purge its own data.
Offcourse it could be purged through an external process running outside of

Hi,
Just a quick question... As it stands right now in our application when all
tasks of a process instance have ended i see in the db a date filled in at the

all data from the db belonging to that process instance,

Just a tip too, since we found out the hard way...
If you are using MySQL as a database dont use a mysql-connector.jar below 5.16
or you will get problems with the prepared insert statements ie they dont work

yeah correct for the suplied jBPM ddl script to work, you have to change all

I am also sorta debating on what route to take on this scenario. So we have
