[jboss-user] [JBoss Seam] - Raising an event in Seam without violating EJB's concurrent

[tonylmai]

Hello,

I am trying to raise an event inside an action which is modeled as a stateful session bean. This resulted in violation for concurrent call in EJB.

Is there a way that I could raise an event in Seam without violating this EJB rule?

Thanks
