Hi,
I find a lot of the answers here relate to the BPMN2 xml with ioSpecification etc. I use the BPMN2 designer in Eclipse and the property sheet does not have the io mapping used in all the answers here.
So an example of what goes into the property sheets for the Process and for each of my WorkItems to allow me to pick up parameters from the Process and then put them modified back into the Process would be a great help.
I have tried adding parameters in my Workitems with the same name as those in the Process parameters to see if a Global scope might pick them up, but no good. Then I tried to programatically get them inside my workitem, but running from gwt-console there does not seem to be a way to call a constructor that passes in the Stateful session. I could not find a way to get the session from the WorkItemManager, which to me seemed like the sensible solution. The documentation does not seem to cover this either.
Any answers?
Thx.
Ed.

[jBPM] - Console + Designer = jboss OutOfMemoryError: GC overhead limit exceeded

Hi all, I would like to collect experience/comments on this issue, occurring at random but very often in my case.
I have just two simple processes in Guvnor, 8 nodes each. One is BPMN2-ExclusiveSplit and the other is very similar.
The defaultPackage has been successfully built.
I can either run the Console to list processes, or I can run the Designer to view process definitions, edit them and rebuild the package.
But as soon as I switch from an application to the other, soon I get a jboss error as reported in the subject.
>From that point on there's no way to proceed until I stop/restart jboss. I tried to logout from both application and to reenter: no way.
I also tried to set -XX:-UseGCOverheadLimit, without any success. Things get blocked soon because of "java.lang.OutOfMemoryError: Java heap space".
As an example of a failing sequence:
- start the designer, select defaultPackage, list processes.
- open both processes.
- from the browser go to the rest url /gwt-console-server/rs/process/definitions, getting:
