No JBPM Context during Seam Remoting calls, what gives?
Hi all,
I'm having a hell of a time trying to get jBPM and Seam works nicely together regardless what have been touted in documentations. Here's the latest issue I found. Not sure if this is by design or a bug.
I have a method on a stateless bean annotated with @CreateProcess(...) and @WebRemote It works fine when I invoke through an h:commandButton, but when I call it through Seam Remoting, it didn't throw any exceptions, but it didn't create a jbpm process instance either.
I tried taking off the @CreateProcess and instead, create the process instance manually through ManagedJbpmContext.instance().getGraphSession().findLatestProcessDefinition(), then I'll see this exception:

The Seam manual doesn't mention any differences between transaction management on Seam Remoting calls so I'm a bit a loss with this issue.
It's strange how wonderful Seam is until I start hitting into these issues with jBPM integration. Thanks for your help!
