Re: [jbpm-dev] [rules-dev] Drools 5.5.0.beta1 \ jBPM 5.4.0.beta1
by Michael Anstis
Hello,
FYI, once the Designer-Guvnor REST issue is resolved I will be pulling from
remote\master and re-start 5.5.0.Beta1\5.4.0.Beta1.
Therefore, any changes pushed to remote\master will now be in 5.5.0.Beta1.
Please be sure to update the N&N accordingly (if applicable).
CC'ed jBPM-DEV for information.
With kind regards,
Mike

Help with ht problem? (Re: BZ 853019)
by Marco Rietveld
Hi Maciej and Mauricio,
I'm struggling to find a good solution for a problem and was hoping to
get your advice about the following.
The human-task service uses it's entities as DTO's, namely the Task
class/instances.
However, we use Hibernate, which uses lazy-loading, which means that
Hibernate substitutes proxy instances in collections until the actual
collection elements are needed.
With Hibernate 3, we miraculously were able to avoid any large problems.
However, testing with EAP 6 has uncovered situations, primarily with
postgresql, in which this strategy (entity as DTO) just won't work.
The problem is that even if all the "persistence" work is done in one
tx, the collections are still lazily-loaded. That means if a task
service operation has to return a Task instance, that the serialization
of the Task object (when it's being sent) triggers the loading of
entities. Due to postgresql's Large Object facility, this means that
there needs to be a transaction around this action. Because we don't
surround the session.write(resultsCmnd); operation with a tx, we get an
exception.
(To tell the truth, I don't understand why this worked with Hibernate 3.. )
As I've been writing this, I've come up with a couple of solutions:
1. Turn off lazy-loading for all entities.
2. Force the loading of all relevant entities by going through the
object tree (task.getPeopleAssignments().size(), etc.. )
3. Put a transaction around session.write(resultsCmnd);
Option 1 has a big impact on performance, especially if we start talking
about high-volumes.
Option 2 has a slightly larger impact on performance but Option 3 seems
a little bit ugly to me.
Are there any options I missed? Any advice or comments?
Thanks,
Marco
PS. This is (IMHO) one of the reasons we need to rewrite human-task.
I've been working on a proposal/POC, but the important thing is that
certain problems that we have now aren't also present in the rewritten
version.

Catching exceptions in jbpm 5
by Giovanni Marigi
Hi,
my question is about catching error events in jbpm 5.x
Watching the examples and reading the docs it looks like I can define a
<boundaryEvent> only inside a SubProcess <subprocess>
Is this a limitation? Does it mean I can't define a <boundaryEvent> in a
process?
How to handle exceptions (for example jbpm exception) in a process
without using a boundaryEvent?
Thanks,
Giovanni
