No routes found for event handler
Hi,
I have been trying to track down a problem with event handlers. When I
send a message to an event handler the message ends up being saved to
the database because no routes could be found. From debugging I can see
that org.apache.ode.dao.jpa.CorrelatorDAOImpl addRoute is being called
for the expected operation however when the inbound message is processed
the query in findRoute returns an empty result set. Any ideas what might
be causing this? Attached is the process and a soapUI test to reproduce.

Hi all,
I submitted a jira (https://issues.apache.org/jira/browse/ODE-634)
for the various troubles being had with event handlers, messages not
being received and conflicting receives. The short answer for what the
problem was is that the message routes were not always being persisted
and the conflicting receive was the result of a race condition. A
potential patch is attached to the jira.

It looks like when the event handler calls
org.apache.ode.dao.jpa.CorrelatorDAOImpl addRoute it is not being
persisted. Putting an explicit call to EntityManager flush resulted in
the query being able to find the route. However I have not been able to
discern why the receive activity's route is being persisted but not
event handlers.
Anyone have any insight that might help explain this behavior?
