[ https://jira.jboss.org/browse/JBRULES-2681?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Gustavo Tenrreiro updated JBRULES-2681:
---------------------------------------
Description:
After an event is processed the session fails to load using JPA persistence.
I ve attached a test case.
It uses a Drools flow file, and a drl file. Both very simple..
The flow file has a "Start" then an action that prints a message to the console, then "End"
The Drl has one rule that processes an event:
import com.kgcontrols.services.company.standardsRequests.workflow.events.VoteCreatedEvent
declare VoteCreatedEvent
@role(event)
end
rule "testEvents"
when
VoteCreatedEvent() from entry-point "VoteCreatedStream"
then
System.out.println("--------------------------- YEAH the event got here");
end
I can see the "YEAH the event go here" on the console so I know the rule fired. But after that, if I try to load the session from the database I get:
--------------------------- YEAH the event got here
